Earlier today I went shopping at a local home improvement store. As I walked in the parking lot to the store entrance, a group of three 20-30 something year old men were leaving. About 20 yards away, one of the men sees me and shouts : Big Man ! ....Big Man !..... Big Man ! (It was as if he had never seen a person over 6 ft. before) I just smiled in acknowledgment and kept walking without saying anything. I am not surprised by such comments, since I have been 6' 6" tall most of my life and I am used to them.
I was not offended when it happened because I was not wearing make-up and carrying a purse. I was wearing jeans and an over sized sweater. I like to think that I was dressed gender neutral. After I have my FFS and I dress more feminine, I hope my reaction will be the same as today's, in a similar situation. I'm expecting to be called "Sir" by some people, regardless of my feminine appearance, simply because of my height. I have heard stories about many tall genetic females being called by the wrong gender pronoun because they happen to be tall.
My best friend said that I would be called "Sir" occasionally after my surgery. I feel prepared for the times it will happen. I refuse to let people mistaking me for the wrong gender to get me angry or depressed.
