That… doesn’t sound right. I don’t think that’s associated with introvertism/introversion. I’m an introvert, I’ll be damned if someone hands me food that was not ordered by me and me not say something. Especially if I’m craving a specific food before I even show up to the restaurant.
Hm… I’ve always been introverted. However as a teen I’ve gone to high school parties with my friends, gotten drunk, smoked weed, hung out with friends, talked to girls… I’ve gone to night clubs, bars, theaters, and restaurants… the way I see it is if I’m with a crowd of people I personally know, I’ve grown up with, or simply my family members, I don’t feel introverted. My energy is focused on them not everyone else outside of my crowd. But put me into an environment where I don’t know a single person and I’m expected to have dialogue with them? Eh… that’s a different story. That environment will definitely spend away my mental energy - UNLESS we’re all having a conversation on a subject I can definitely relate to. If it’s an enjoyable dialogue, then I walk out of that environment feeling just fine.
