I might as well answer my own question, no?
You have to be extremely close to me to get a snip of how I feel about you. If I don't know you well, that's not easy for me to throw around. I've only, maybe, told three people how I felt about them online. If I don't know you too well, then yeah, I won't tell you how I feel about you. It's not that I don't care; I just feel like it's better to reserve to the people I feel closest to. Of course, though, I'll let you know if I think you're cool/sweet/nice, but there's very few people that I've literally said how I really feel about them. It's not a one sentence thing for me.
And there's barely anyone I don't like, and even if I did, I won't tell you because that's mean.
But..,I suppose if a person is down and need encouragement, I'd tell them what I think of them? I just have a hard time voicing opinions like this without feeling like I'm trying too hard.
