Ответьте пожалуйста на вопросы.
I lived apart from my family when I was at sports camp. Our athletic team — eight lads — shared one big room. You may think that it's not easy when there are so many people with different personalities around you. Nothing of the kind! All you need to do is to think about the other seven people. We even worked out a list of rules that helped avoid quarrels.
• Don't speak too loudly and don't play loud, music in the room if it's not a party (because there might be somebody who feels sleepy or who is trying to concentrate on reading or something tike that).
• Don't occupy the toilet or the bathroom for more than ten minutes.
• Don't ask too many questions if someone wants to be left alone for a. while.
1 How does Rick feel about sharing a room with seven boys?
2 What's his secret for sharing a room without quarrels?
3 Can you add anything to his list of rules?
