A college student writes to his parents:

Dear Mom and Dad,

I feel miserable because I have to keep writing for money.  I feel ashamed and unhappy.  I have to ask for another hundred, but every cell in my body rebels.  I beg on bended knee that you forgive me.

Your son,
Marvin.

P.S. I felt so terrible, I ran after the mailman who picked this up in the box at the corner.  I wanted to take this letter and burn it.  I prayed that I could get it back, but it was too late."

A few days later he received a letter from his father.  It said:

"Your prayers were answered.  Your letter never arrived!"
