     It's easy to make you embarrassed (窘迫的). You may run into the wrong classroom and everyone
looks at you. Or you have a piece of cabbage in your teeth! What do the American and British teens find
embarrassing and how do they react (回应) to it?
     One big embarrassing thing for them is answering personal questions. If you ask "How old are you?"
or "How much money do you make?", they'll get angry. It's polite to stop asking. If you meet someone
for the first time, talk about something not personal, such as your neighborhood or school. British people
love to talk about weather.
     British and American teens feel embarrassed if they still rise their parents'money to buy clothes or
have to ask their parents before making a decision,because others will laugh at them.
     In some situations, if you look bad in public, don't worry. A child may forget and call his or her teacher
"mom" in class. A good laugh is a good way out of it! Sometimes you find that you don't have enough
money when you pay at the supermarket. Just put some things back quickly. If you explain too much,
you'll attract a lot of attention! 
     Honesty always works best. If you forget the name of a person, or don't know how to clean the toilet
after using it at your friend's home,just ask them about it.
