I'm with you. I'm one that sees both sides of most things and doesn't like to talk if there's no point for me to make. I also don't like repetition, so if I see another comment that's in line with what I'm thinking, I find I physically nod (because everyone can see me, right? lol) then I scroll on instead of repeating it. I also lack social skills unless there's room for sarcasm or dry humor, so I try to be careful with that as well.
