     With the holidays coming up, lots of people will be having parties. Want to make sure you're a perfect

host or guest (客人)? Now it's a good time to brush up on your party manners.

     When inviting guests to your party, send invitations to their homes instead of passing them out at school.

This way, you won't hurt the feeling of classmates you didn't invite.

    <3>Wait for all your guests to arrive before starting any activities. If people at the party don't know each

other, make sure you introduce everyone.

     If your guests bring gifts for you, thank each gift----giver as you open his/her present. After the party, be

sure to send a hand-written thank-you card to each guest, telling them how much you appreciate their gifts.

     When you receive a invitation to a party, be sure to let the host know whether you can come.

     Arrive on time. Bring a gift to a birthday party. <4>If it's a holiday party, ask the host if there's anything

you can bring. Adults often bring a desert or a bottle of wine to a party, even when the host tells them that

he/she doesn't need anything. Young people don't have to do this, but it's always polite to ask.

    Be friendly to the other guests. Remember to say "Please" and "Thank you"! When you leave, thank the

host for the party.
