One one hand, that makes sense, but things kind of change when we apply this reasoning to an ADULT who wants Teach's attention. Imagine if Teach ignored one of the parents. Maybe a parent had a joke to tell or wanted to just comment on the teacher's hairstyle or whatever, and patiently waited, but Teach just walked past the 35 year old to speak to another parent, then afterwards passed the 35 year old in the lobby without eye contact or anything. LW2 is wrong to think anything is wrong with her daughter; the daughter handled it well, whereas many other 6 year olds would have shrieked or yelled to get the teacher's attention. The girl should be taught to say, "Excuse me," to begin her socializing.
