     I was parked in front of the mall wiping off my car.I had just come from the car wash and was

waiting for my wife to get out of work.

     Coming my way from across the parking lot was what society would consider a bum.From the

looks of him, he had no car, no home, no clean clothes, and no money.There are times when you

feel generous but there are other times that you just don't want to be bothered.This was one of thos

e "don't want to be bothered times".

     " I hope he doesn't ask me for any money," I thought.

     He didn't.He came and sat on the edge of the pavement in front of the bus stop but he didn't look

like he could have enough money to even ride the bus.After a few minutes he spoke.

     "That's a very pretty car," he said.

     He was in rags but he had an air of dignity around him.His badly-grown blond beard kept more

than his face warm.

     I said, "thanks," and continued wiping off my car.He sat there quietly as I worked.The expected

plea(乞求) for money never came.As the silence between us widened, something inside said, "ask him

if he needs any help." I was sure that he would say "yes" but I held true to the inner voice.

     "Do you need any help?" I asked.

      He answered in three simple words that I shall never forget.We often look for wisdom in great

men and women.We expect it from those of higher learning and achievements.I expected nothing

but an outstretched dirty hand.He spoke the three words that shook me.

     "Don't we all?" he said.
