Exactly.I am the same. I feel like I have to watch what I say but it is more because I can be kind of blunt, which I think could come off as "mean" at times, since there's no facial expression and/or mannerisms to accompany it. I worry that I'll be misinterpreted or worse offend someone or hurt their feelings without meaning to.
