While at a children's museum today with dd and a friend and her two kids, I blocked a stranger's child's hand from hitting my friends dd in the head for like the 10th time. (He'd also hit my dd too, but i guess she didn't react as fun because he went back to my friend's). He then just looked at me, so I said "that is not nice, if you want to play and touch her nicely you can." He just stood there for a few minutes and then ran across the room to his mom. Where were his parents while this was going on anyway? Geez.
