Only a little mistake

Well my son thoroughly hates me now, but I think I might deserve it. He wanted to have a sleep over and to invite a couple of people over rather than the traditional one person that you usually have which I was fine with . He gave me a list of kids that he wanted to have come over and said he would talk to them to see if they were interested. Being the mother I am, though, I thought I would try to help him out by sending invitations and directions to our house. So after going through my pile of invitations, thank you cards and sympathy cards, which all mothers have, I found that the only invitations I had were generic invitations with the Smurfs on them or Kentucky Derby Party Invitations that I have had for years and never used. Well they didn't get used this time either.
