Abby and Angela are sisters.

Thanks for showing me how to set up a FriendLink. It's fun!
Yeah, I thought you'd like it. I especially like to keep in contact with camp friends this way.
I know! Most of my friends on here are from camp!
Cool.
Hey, cool. You are in the other room, and I am writing to you on this.
You're funny. I think it's more fun to leave messages for people you don't see every day...Try that!
