     When you're invited to have dinner in a foreigner's home, please remember the following:

     At table, when the hostess (女主人) picks up her napkin, you may pick up yours and put it on your legs.

     If a servant (佣人) passes food around, he will pass the dish to you at your left hand so that you can easily

serve yourself with your right hand. Never serve yourself while the dish is on your right; it is then the turn of

your neighbor on the right.

    Do not reach across the table or in front of someone to get something-that is not polite. Ask him or her to

pass it to you.

     There are things in the middle of the table, such as bread, butter and candies. You shouldn't take any until

the hostess tells the servant to pass them to you.

     Do not leave your seat without saying anything. If you need to leave the table to go to the washroom or

do something else, you should say "Excuse me for a moment, please."
