Actually TurtleDove, a few years ago, I did have to tell a woman in the neighborhood to leave my DD alone. She was in her early 30's but for some reason, she kept wanting to get buddy buddy with DD and 2 other little girls. She would always offer to show them her pet rats and take them to the playground. I had to step in when DD was getting flustered because every time she went out to play (she was 11) the woman had to come over. I did try to talk with the woman to get a feel for why she wanted young girls as friends, but she was evasive and strange, so I finally did tell her to please leave my DD alone (as did the other mom because she was getting frustrated by the attention).
Again, I did not run, yell, or cuss at the man, but was very sharp in my tone because I see no reason for a man who, yes I do see everyday in the neighborhood, to suddenly stop and ask my DD, who was on a partially secluded porch at least 30 feet back from the road, if she wanted ice cream. I will concede to the majority that I over reacted, but it just seemed weird.
