DEAR ABBY: A few months ago, I found out my adult child is transgender. Nobody knows yet except for me, my husband and my other child. Until this year, I have always worked in a very caring, loving and supportive environment. Recently, I overheard a new male co-worker say in a high-pitched voice, “I’m transgender! I’m transgender!” while spinning in circles and waving a scarf around his head. I was floored.
