Yes, yes it is. Homo sapiens is a pack animal. You interact with people on daily basis, from buying milk to job interviews and parties. And that is not a skill you are born with. School systems throw you in a group of people usually far larger than you are used to, and that group never consists of only people you like. It's a seemingly hostile environment, and you are forced to adapt to it, so that later on politely asking a stranger to move a bit to let you pass doesn't turn into unmanageable task. Oh, and I fear for a generation growing up with ability to block/ignore interactions with people they dislike being a mere click away and never really having to reconsider their words for fear of getting their face punched in.
