I dunno. It's complicated. I'm an introvert but I feel a draw to interact with some folks, just not all folks. If I see some introverted nerds that look like they would laugh at my jokes I am here for it.
If it's a crowd of folks I don't think I would have much in common with I could just as easily keep walking. No draw for me.
And then some folks are just intimidating, so I keep my distance unless I get pulled in. It's a dumb reaction but it comes from a place of respect. Like senpai notice me type stuff.
