thoughts

Well I'm studying english and I got into an argue with my professor about a certain sentence he translated from german into english. The topic was "subjectivization", which means you pick a certain word in a sentence and make into the subject of the sentence.

Example: "It will be sunny in London today."
By using London as the subject and removing the it-dummy-subject it could be rephrased into: "London will be sunny today."
This can rarely be done in german so it sounds very confusing.
The sentence we had a debate about was really odd, though.

"Four people can sleep in this tent."
My prof rephrased that into: "This tent sleeps four people."

So, native speakers, I need your help. Does this sentence sound weird to you as well? Do you think it is grammatically correct? And most importantly, would you say that?

I'm not the kind of person who feels the need to express himself online too much (see my post count/date of registration), but I got into a situation where this could help me.
A few weeks ago one of my friends died because of Leukemia. It's not like we were best friends, he was just a great person to have fun with and I won't forget the 2 holdays we spent together in the Netherlands. I heard about his disease about a year ago and was shocked, but I thought to myself all would become fine eventually. I kept myself informed by talking to other friends of him, but I never went to hospital to visit him. I don't know why, but hospitals disgust me, I just can't look at sick people and never would I want to see my friend that sick.

So, 3 weeks ago I got a phone call and one of my friends told me he died. 2 weeks before that phone call he got out of hospital and we had a barbecue. I remember him joking about his disease, saying stuff like "If I didn't get Leukemia, I would have never experienced how handsome I look with a bald head" or "The doctor told me I could continue to smoke Marijuana because that is shit compared to the drugs I get from him", making all of us laugh - guess that was his way to handle his disease. He never talked to me about how I didn't visit him in hospital, I guess he understood.

Since the funeral however, I have a really guilty conscience. From time to time I look at photos of him and just think about how fun it was spending time with him. I've never had this feeling of guilt and I have no clue how to handle this.

I hope it helps writing my thoughts down. I didn't create a topic, because I wouldn't want to start a discussion about my behaviour. This will most likely be my one and only blog entry, I hope I didn't depress you.
