Did you figure it out?

Yesterday I posted the following riddle:

How is a cat different from a comma?

Today, I get to pick a random person who wanted to play the game so he/she could guess the answer.  If that person gets it right, he/she wins a signed MAKE BELIEVE bookmark.   The only thing I asked is the person not cheat and look up the answer.  I have to trust that you didn’t.  Ok.  so who will be the first lucky contestant?

Hmm, let me dig around here in my hat full of names…and the 1st contestant is…

Vanessa Chapman

What say you, Vanessa?
