I tend to assume that I don't come across very well.
But if I dwell on it, that only makes things worse, so now I try not to worry. I just do the best I can, which is better than lying or not saying anything.
In some jobs, straight-talking is considered an advantage! Everyone seems to be quite blunt in my office so it's not too bad.
Cheer up, Hale_bopp!
