     A letter to Edward,a columnist (报刊专栏作家)

     Dear Mr Expert,

     I grew up in an unhappy and abusive home.I always promised myself that I'd get out as

soon as possible.Now,at age 20,I have a good job and a nice house,and I'm really proud

of the independence I've achieved.

     Here's the problem:several of my friends who still live with their parents wish they had

places like mine so much so that they make mine theirs.

     It started out with a couple of them spending the weekends with me.But now they seem

to take it for granted that they can show up any time they like.They bring boyfriends over,

talk on the phone and stay out forever.

     I enjoy having my friends here sometimes-it makes the place feel comfortable and warm

but this is my home,not a party house.I was old enough to move out on my own,so why can't

I seem to ask my friends to respect my privacy (隐私)?

Joan

Edward's reply to Joan

     Dear Joan,

     If your family didn't pay attention to your needs when you were a child,you probably have

trouble letting others know your needs now.

     And if you've gathered your friends around you to rebuild a happy family atmosphere (气氛)

,you may fear that saying no will bring back the kind of conflict you grew up with-or destroy the

nice atmosphere you now enjoy.You need to understand that in true friendship it's okay to put

your own needs first from time to time.

     Be clear about the message you want to send.For example,"I really love your company but

I also need some privacy.So please call before you come over."
