Maybe I could fix the worst one. I flipped open the Yellow Pages and called the first dentist within walking distance. The receptionist told me to come right over. As I hurried across the campus, I forgot the pain in worrying about how I would pay the bill.

In a few minutes I was in a chair being examined by a dentist who said, "Hmm!" as he surveyed the wreckage of my mouth. "Your teeth are in bad shape."
 

"I already know that," I snapped, in a smart-aleck way to hide my fear.
 

"But don't worry, I'm going to fix them."
 

"No, you're not. I can't afford to pay you." I started climbing out of the chair.
 

"What are you doing?"
 

"I told you, I have no money."
 

"You're a student at the university, aren't you?"
 

What difference does that make? "Yes . . . "
 

"You're going to graduate in a few years, aren't you?"
 

"I hope so."
 

"Well, then you'll pay me. Meantime, you concentrate on your classes and leave the dentistry to me."
 

I stared at him. He really meant it. He calmly picked up his tools and fixed the aching cavity.
 

From that day on, I saw him every week until my teeth were in good shape. And he kept them that way with regular checkups. After graduation, I got a job and settled his bill in a few months.
 

In the 40 years following, I've learned to call this man a "woodwork angel." These are strangers who appear out of nowhere--out of the woodwork--when I need help. They've lent and given me money, materials or equipment; they've taught me skills and helped me organize groups; sometimes they've rescued me from danger or making a big mistake. So, dentist dear, wherever you are, bless you and thank you again!
