Don't ya just hate it when you're trying to tell a joke and they start laughing before you get to the punch line.
This little girl definitely reacted to her daddy when he started laughing. Nothing wrong with him laughing, shoot it was funny, but it is really interesting to guess what she was thinking. That look comes over her face (of course she doesn't even slow down talking) and I have to wonder, what was that look ? What did that just mean ?
I sometimes experience the same thing with my wife.
Cheers
