A lot ofpeople don’t want to talk about their age,especially(尤其是)womenover 30.The thought of grow—ing older is a painful(痛苦的)one and most of US,ifpossible,would like to have nothing to do with it.However,getting older is a thing that happens to all of US.As a result,many people work hard to keep young.So the lastthing they want is for someone to askthe question,“How old are you?”
Peoplemay answer this question like:“How old do you think I am?”“30 something.I’min my thirties.Let’s just leave it at that.…‘I can’t remember.…Oh,don’t ask me that.…“A lot older than what lwould like tobe.”
However,if you really want to knowsomeone’s age,this is how you could find out the answer.First you estimate(估计)their age.Then you subtract(减去)ten years from thatestimation.Certainly you will get a big smilefrom thatperson who will also say.“Wow.Youare my best friend.I’m 38 already.Can you believe it?”You,ofCOUrSe,,say,“N0.I reallyCall’t.You’re,joking.You don’tlook a day over 28.”
Most of men are pleased totell others how old they are.
