Do most ESEs regularly ignore people, or just the ones I know? I've noticed this mainly with one ESE I know in particular, and others have noticed it with her as well. She's been known to:

1. Ignore people standing right beside her, while still happily talking to other people in the same group.

2. Reply to Facebook wall posts from some people, but not others.

3. Exchange an e-mail or two, and then suddenly stop replying mid-conversation.

Most people I'm familiar with, even if they don't want to talk to you, will at least politely acknowledge you in some way. I've never encountered this sort of complete ignoring of people before. I would tend to assume this sort of thing was a deliberate snub, except the same people she's ignored one day, she will happily talk to like old friends the next, and go back to ignoring the day after that.

Has anyone else experienced/observed this sort of behaviour from ESEs? Is it common among ESEs, or is this an isolated case? Any ideas on what might cause this? I have a few theories, but none of them really explain all the data.

It's very confusing.
