Begging letter

A college student wrote a letter home:

"Dear folks,
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 came!"
