Catie Birthday party invitations

Catie's birthday party is coming up, so we went and bought the invitations. She was so excited! When we got home, I had to get Allison down for a long overdue nap. While I was in trying to get Allison to take a nap, Catie came in and asked if she could open her invitations and I said no, we'd do it when I came out. When I was finished getting Allison down, I went out to find that she had stuffed all the invitations into the envelopes and licked them all closed, without writing the info on them obviously.
