Only six people that I can think of call me by what some people called me when I was younger. It is not creative, it is just adding a Y, like calling someone named Patricia Patty, or someone named Cynthia Cindy. None of the people who still call me that are relatives, unless you count my husband, but he did not know me as a youngster. My dad was one of the people who used to sometimes call me by that nickname, but he doesn’t now, and stopped a long time ago.
When someone calls out for me by that name I don’t instantly realize they are talking to me it is so infrequent. I would have to recognize the voice, or maybe if they said it a few times I’d realize they were trying to get my attention.
I’m fine if someone wants to call me any version of my name, but the childhood version with the Y on the end I don’t really identify with. If you ask me what I prefer or am accustomed to, it is either my full name or the very short version like Pat for Patricia.
