I was a single divorced Mom raising my two young children alone. They went to their fathers for visitation during the summer as we lived in MD and he lived in MA. Anyway I asked my daughter who was around 8 at the time why when she went to her Dad's she was on her best behavior for him and when home with me I got the the mouthy butt-head who always argued and wouldn't do as she was told? Her answer...."Cause I know you will love me no matter what".
