I hope the conflict is working itself out. We are trying to avoid the "some people are mean and you just have to ignore them" message for this situation. For one, it is a small class and there is a lot of school year left. Secondly, if he thinks of them as "bad guys" I think the peskiness will likely continue. We just told him to be nice to everyone and if they are not feeling friendly, they might be friendlier on another day. He seemed to accept this idea. He said he asked one of the "guys who don't like me" to build with him and he did. This small victory lead him to think maybe last weeks upset was a "misunderstanding".
As for the teacher, I don't think she would have brought it up as being a big continuous disruptive problem or anything had I not approached her with questions about what was going on. While I didn't say it, my tone probably said "Why are these meanies making my baby boy cry and why are you letting them?". She was probably a little worn out from dealing with kindergartners all day, maybe low on caffeine and had just dealt within the last half hour my son having to leave the room because he was crying so much. I am inclined to cut her some slack on a less than awesome response. We'll see how it goes.
I am super proud of my little man for handling such a rude response at the start of class and for later reaching out to invite one of the mean boys to join him when the boy looked like he wanted to play with the blocks my son had. It takes some courage to risk rejection to do the right thing.
