I'm not at first glance.
I'm big and heavily tattooed with a crazy hobo beard. I'm also not a big talker, prefer working to talking most of the time.
So, people tend to be intimidated at first. Once they know me, all good though.
Some of my favorite people have admitted to being terrified of me based solely on appearance and bearing.
Would be lying if I said I didn't use that reaction to my advantage though.
