If it feels like a slight, it most likely is.
Do you ever catch these same people smirking? If so, that's definitely what it is.
Best to just ignore it. Reacting to that crap just gives them what they want. It's childish behavior even by NT standards. It's unacceptable childishness, but the only good way to handle it is be the adult among them, and don't react at all.
People like that are true emotional infants.
There is a lot more power in letting them think you have no idea what they're up to. You know something they don't, but they think it's the other way around. Just know that. That alone is self-empowering.
Opinions of people like that are worthless.

I'm not likely to be around much longer. As before when I first signed up here years ago, I'm finding that after a long hiatus, and after only a few days back on here, I'm spending way too much time here again already. So I'm requesting my account be locked, banned or whatever. It's just time. Until then, well, I dunno...
