"Mommy, what is a face book?"
"How did you lose your face book?"
"Oh, you mean when I was talking about when I lost my Facebook last year?"
"Yeah, where did it go? How are you going to find it?"
"It got lost on the computer, so I made another one."
"Oh......... ok. I'm sorry you lost your face book."
Caleb overheard me talking about when my Facebook account disappeared around this time last year (my own stupidity - don't ever try to change your email login to an address that is already being used by another person to log in the Facebook. In this case, it was mine and Greg's shared email account. It caused my account to be deleted) He was very concerned about my lost book. The difference between generations!
