so my dd is in gymnastics. she is 6.. there is this other little girl in her gymnastics class that goes to her school. at gymnastics they seem to get along very well, playing together before class etc.. well my dd came home from school today telling me this girl is being nasty to her at school.. calling my dd stupid and ugly.. which is very upsetting to my dd. (she has trouble socializing to begin with)... is it normal for kids to get along in one setting then not another? I just dont understand why this girl is being so mean when they get along elsewhere.
