     I took my dog, Phil, to the vet's (兽医诊所) yesterday. When the doctor came into the room, he was

limping (跛行).

     "What's wrong?" I said. "Oh, it's my knee. They want me to really appreciate the operation I'm about to have, so they delayed it another month, so I would suffer more," he replied.

     It was then for the first time I actually showed my scar to someone. "Look, I had an operation on my

arm." My wife has been telling me that it really didn't look bad. It healed very nicely. When I showed it to

the doctor and his assistant, they said, "That's terrible!"

     That's when I discovered something.

     "Doctor, when I was a kid, I fell. I remember showing the scar to all my friends because I thought it

was 'cool'. Having a scar at that age was like having a battle injury."

     "Then I went into the young adulthood and vanity (虚荣心) took over. I was in a band and never

wanted anything to scar my beautiful face. Now, at 59, I just joined that group of older folks who are

proud to compare operations, aches and pains," I said struggling to get it out without laughing.

     The winner is the one who is in the worst shape, I guess. Then there are those at any age, who use their scars as an excuse. The kind of excuse holds them back, limits them and provides a crutch for why they

aren't happy. "Too short"... "too fat"... "my family"... "ever since we had children" and so on.

     All scars never heal because we keep picking at (扯拉) them. I promised I'd never do that, yet today I didn't even hesitate to show the doctor my scar. It's okay. I see it as returning to my childhood. What

scars do you have?
