Oh blah, Bridget. It's hard enough to have her so far away and miss her, let alone with DBF being a weenie, as if her "not listening to him" has anything to do with YOU.

She's a GOOD KID, of course she's going to listen to him when he's the only "authority figure" around. It sounds like he's actually stepping up to be a parent when you're not there, so she's responding to that. When you're there, he doesn't, so she doesn't pay him any mind.
I would hope that everyone is laughing because she's just so stinking CUTE and not because the "joke's on you." It will be nice to have her home!
