The First 3 Letters Of Your Name

"To the young lady I met on Wednesday, I was very pleased to meet you. I would very much like to see you again. Please write the first three letters of your name on this note if you feel the same. -Charles"

I found this on a note taped to a telephone pole in my neigborhood.

Superman

There's a little boy on my street who everytime I see him he is in a Superman costume.
