Advice

Hi ______,

Why should your parents do all the washingup?You should help around the house—it's only fair. I don't think you should change your looks though. Young people should look like young people.

Hi______,

Wearing your hair pulled back in a ponytail (马尾辫) will help keep it out of your mouth. When you feel like chewing something, try bubble gum (泡泡糖).Give yourself time and you should be able to break this habit. The first few days are usually the hardest. Good luck!

Hi ______,

Don't worry about it so much!Phone your friend up as usual and she won't be able to refuse you. I am sure you will get along well with each other. Everything will be fine.
