Wow, I dont blame you, I would be upset, and hurt also. If Grandma decided that she wasnt able to keep Morgan, She should have called you not just sent her home with dad, And he should have had the decency to stop or at least call you before he went home to say Hey, I got Morgan you want me to drop her off.
Sorry but I think that was very inconsiderate of him to do..
*hugz* Sorry I brought it up
