FYI, my son was asked to go to a lunch bunch in K, organized by the school counselor. Fwiw, at our MCPS school it is not really a reward; evidently teachers recommend kids who they notice having social difficulties of some kind. I ended up meeting with the counselor because I was sort of upset that no one came to me first; he explained that just about every kid in K has some adjustment issues, and that his lunch bunch included everything from girls who hugged too much to boys who were discipline problems. In the end, my son loved the lunch bunch; the counselor is a very popular figure at the school so it was a huge treat. I'm not really sure if it helped his social awkwardness, but I'm glad he did it. If you're still concerned, just ask - I'm sure they will explain the rationale and the purpose.
