I used to be friends with this girl who let her kid run wild. She brought him with her and her husband one day to see our new house, and he went crazy! I spent the hole time on pins and needles, waiting to see what he'd do next. His mother didnt' do much of anything...all she said was, "Oh, isn't he cute?" I wanted to scream.
Yeah, this couple came over to our house once with their toddler. She found my husband's baseball bat and started walking around the house, swinging it. Her mother saw her, but did NOTHING. My husband had to wrench it from her before she broke something or hurt someone. Then she screamed because he took her new toy away from her.
It's pretty sad when you have to watch someone else's kids, and the parents are RIGHT THERE.
