Well, I certainly can be one on occasion. I try to limit my inclination to do harm when I feel the urge, but on occasion it bursts free of the bonds I place on it.
It did so on Twitter today, with someone who had already shown they were sensitive. I made an apology as public as the original comment, but don't know if I was read. Beyond feeling abashed at the statement I made, I cringe at the thought I might be considered a troll or worse yet, a 'social media bully'.
Ah well. It's a new frontier, and I, like everyone am bound to make mistakes.
I shall be sure to own them all as I do all my past ones.
