He starts to clean up a little, and then he hear steps down the stairs. Anna Scott comes down with new clothes, a black top and a skirt.

And then Spike comes in, walking right past them. "Oh William, I have something to say! You are never going to believe me" William doesn't think about Spike, all he can think of is Anna Scott, standing in his doorway. She says goodbye again, but this time, she kisses him. He can feel the softness of her skin, he can feel the smell of her hair. Then she lightly touches his hand, and the leaves. On the evening, William and Spike watches some movies. Starring, Anna Scott. Then the feeling of sadness hits him again, "I'm never ever going to see Anna Scott again" He thinks

Fördjupning - hörselskador

Vanliga hörselskador är, Tinnitus, Menière

Tinnitus 

Tinnitus innebär att man kan höra ljud som inte har någon känd källa, dessa ljud är ofta väldigt gälla, störande och stressande. Ungefär var tionde person i Sverige har erfarenhet av tinnitus, de vanligaste anledningarna till att man får tinnitus är bullerskador och hörselnedsättning på grund av att man har blivit äldre. Ljudet kan uppfattas olika från person till person, men det vanligaste är att man upplever en högfrekvent ton, alltså en ton med väldigt hög frekvens. Men man kan uppleva flera olika ljud, till exempel ett tjutande, susande eller brummande ljud. 

Behandling 

Det finns inget vetenskapligt bevisat botemedel mot tinnitus, men de som har tinnitus blir bättre av sig själva efter en tid. Om man söker hjälp så får man örat undersökt, varför besvären har börjat. Och det kan vara så att man har en bestående eller en tillfällig hörselnedsättning, och då bör en läkare utree´da om man har en hörselskada eller inte. 

Menière

Menère är en yrsel och balanssjukdom, det känns som om omvärlden eller en själv snurrar. Sjukdomen sitter i innerörat och den ger plötsliga attacker av yrsel, tinnitus och hörselnedsättning. Det som händer när man får de här attackerna är att det först slår lock för örat, hörseln bli sämre och tinnitusen ökar, därefter tillkommer illamående och kräkningar. Hörseln blir sämre efter varje attack. Sjukdomen kan vara ärftlig, den går inte att bota men kan lindras genom behandling.

William was late as usual, he couldn't find he's glasses. He was going to the cinema with Anna, and he didn't find he's glasses, he had to take he's goggles. But right after William leaves his lodger Spike found them. After the movie they go for a meal at a Chinese restaurant, they had order a table for two. As they sat down and talked, they could hear a loud conversation at the table next to them. There was a group of men, talking about Anna's last movie. They all agreed that they didn't liked it, and they were talking bad about her. William walked over to the table and told them of, that this is not a good way to talk about a person. The men didn't care about what William said, and they continued talking about her. As Anna and William were leaving, Anna turned and walked right back to the table were the men sat. She said "I'm sure it was all just friendly talk and you didn't mean anything, and you can't help being stupid. Enjoy your meal, the fish is very good". Then she returned back to William, still smiling. At the way home Anna was feeling regret and she said that she didn't know what she was doing, or what they were doing. They stopped by the entrance at Ritz hotel and she asked if he would like to come inside to her room, he said.
- There seem to be a lot of reasons I shouldn't.
- There is, she said. But would you like to come inside?
- Give me five minutes, he said.
Anna walked in to the hotel, and soon William walked inside to. He knocked on the door to her hotel room, she opened, and he kissed her. Anna seemed to be quit worried, she said.
- My boyfriend is in the next room. I didn't think he was coming so soon.
At the next minute her boyfriend was standing behind her back.
- Who is it? He asked.
It was Jeff, a famous film star. William thought quickly
- Eh... Room service, he said.
- How are you doing? I thought you people always wore suits, Jeff said
- Well... Yes, but I've just changed. I'm going home, this is my last call, William answered.
- Oh great, can I have some rally cold water up here? Jeff asked.
- I'll see what I can do.
-And maybe you can clear thees dirty plates while you're here, Jeff said.
William picked up the dirty plates.
- Really, don't do that, Anna said. I'm sure that's not his job, she told Jeff.
- Is there a problem? Jeff asked William.
- No no, it's fine, William said.
- What's you're name? Jeff asked.
- It's Bernie, William answered.
- Well, thank you Bernie. Jeff said as he was pushing five pounds into Williams hand.
And the Jeff turned to Anna, and he kissed her. Jeff left the room.
- I think I should leave, this is all very strange, William said.
- I'm so sorry, I don't know what to say.
- I think goodbye is probably the right word, William said.
William walked downstairs, he had his heart broken, and he was feeling sad.

Two Poems about Love

Writing
What is love or what is friendship?


Love is when you can feel your heart rising when he/she is around. When he/she is the only person you are thinking of. When you can tell that this is right, you can tell that this person is the one for you, the only one that matters.

Friendship is when you have someone you can talk to, someone you know always will listen. Someone you can tell everything, and you know that your secret is safe.
