Similar has happened to me attempting to use a public convenience at a park after a walk. I didn't have any hair at the time, was wearing sunglasses, with no hat, jeans and t-shirt.
As I approached, there was a young boy sitting on the floor between the men's and ladies, obviously waiting for his mum. As I would practically have to step over him to get in, and I didn't want to alarm him, I thought I would say "hello" as I approached! He was still terrified, and screamed "Mom!!", at which point "Mom" emerged, took one look at me, and all but screamed as well! I smiled as sweetly as I could, and she gasped "ooh, you gave me a fright!" Then the small girl with her stared at me, and said "Who are YOU!??"
By this time, I was a bit impatient with the whole bally family, not to mention rather desperate to get to the loo!, so I responded, "Who are YOU!!!???" and continued past them into the building. I was really quite upset. I hate looking like this, and now I have lost my brows and lashes, although my hair is about 1cm, it is very sparse and mostly dead white.
So attractive! 😞
