I don’t have any advice on Word other than what others have said about autotext, but tell that parent that complained that if they can do better to step up or shut up.
I coached my son’s soccer team for 6 seasons (fall and spring each year), and had one parent complain incessantly to the other parents that I wasn’t doing this or that right.
I must have been doing something right as our record over the time I was coaching was something like 40 wins and 5 losses with an average “goals for” around 8 and “goals against” around 3. I had the support of the kids and the other parents so it just rolled off my back.
One day in the middle of a practice drill, he called me over to tell me he was going to write a letter to the soccer association and complain that his son wasn’t getting his fair playing time, which was supposed to be 1/2 the game.
I handed him the whistle and said “have a nice day” turned and walked over to the other parents and said that Mr. Complainer was now the coach. They freaked, he shut up, all was good.
