Random vacation observation: rudeness

I found the behavior of some of the very young kids on the lower pistes to be appallingly rude. Some of them seemed to have no concept of queueing and pushed themselves directly to the front of the line. So far as I could tell these kids were not attached to a ski school, which would have given them some excuse. Where do these kids get their manners? I don't recall running into such behavior in the past. Maybe it's just that we were there at the peak of the season, although it didn't seem too ridiculously crowded.
