Have you ever felt intimidated by someone’s presence?

There’s nothing initially wrong but it just feels off being around them

Yep, I specifically remember a girl in college. She was part of the theater department, she loved acting and singing, had a real passion for it, and always got the female lead in all the shows she auditioned for in the time that I was there. There was something about her vibe that was “off” to me. I never had any reason to believe she was a bad person, we never had any issues, but I never felt fully comfortable around here. To this day, I’m still not sure what it was, maybe it was just her ambition that intimidated me but I always got the sensation that I should stay out of her way.

When I was younger. Nobody intimidates me now. We all put our pants on 1 leg at a time.

Though your question's description isn't really "intimidation". Sounds more like you consider them "suspect". Maybe that is intimidating to you, I dunno.

I'm one of those people, I get that a lot.

I think it's just my looks and facial expressions, but new people at work and when I'm out and about, tell me this all the time.

Until the get to know me...
