But at this point, I think he feels targeted when it's really, honestly just kids being kids. Kids taunt/tease each other when they get out in four square and when they are beaten in a foot race. He thinks it juvenile, says he knows he was out, Anna knows she lost the race, etc. and that it doesn't need to be pointed out. I think at this point we have to just work with him so that he understands that kids ARE juvenile!
My DD is like this. She's not only bothered by it for herself, but for other kids, too. It really upsets her when it happens to her friends, and even other kids she doesn't really know. I think it bothers her much more than it does them, and she does not participate in it. ( But she can be mean as heck to her brother. That's the only setting where I see her do that kind of intentional kid-on-kid aggravation/torment.)
