For school ball this past season, my youngest DD had a former baseball coach as her softball coach. He was enthusiastic, knowledgeable, and a very good guy to play for. The only issue, and minor it was, was in translating some of the baseball jargon to softball. The coach told my DD to go take the mound. It took a while for her to figure out that he meant that she was supposed to go out and pitch.
I still slip with this from time to time. I feel better now that I know I'll NEVER get it right.
