Most Helpful Girl
Depends on what he's saying. If he's bashing someone, or group of people (example: he's a homophob and hates gays) he's gonna know EXACTLY how I feel about his behavior. I can also promise that whatever fluffy feelings I had are now gone.
If he's just acting awkward, or has a different, yet well thought-out-and-presented opinion on something (like gun control laws) we can work past it.
Also if he acted awkward specifically around me, no one else, I'd assume it's because he doesn't care for me and I would probably not go out of my way to make conversation.
