Yet Another Perplexing Indeed Ad

1.  If this guy is regularly losing jobs ("they have to move again..") why does he keep buying houses instead of renting apartments?  How often have they had to move, anyway?  That little girl looks awfully frustrated and angry, like it's a regular thing.  So what's with the constant purchase of houses?  Maybe if they just rented a nice two-bedroom apartment, they'd have enough financial stability to stay in the same area during a prolonged period of unemployment for dad?

2.  Somehow both the dad and the little girl know that the chirping noise on dad's phone twenty feet away means that dad's going to be employed and they don't have to move after all?  How do either of them know what that chirp means?  How did the little girl even HEAR the chirp through the door?
