I rarely had fewer than 5 or 6 other Susan's in my class at school. We were kiddy litter sprinkled all over everywhere. When I was still in elementary school, I thought Diedre was the perfect name for me and no, you would not be allowed to call me DeeDee. In Junior High, I changed my imaginary name to Stuart. Also changed my last name to Caldwell. Often when I met strangers, like on a bus or something, I'd tell them my name was Stuart Caldwell.
When I went to a fancy private high school where many of the girls had been given their mother's maiden name for first name. Brooke, Gray, Marshall... Susan was even stupider sounding there but there were fewer of us.
When I was in my 30's, I got online for the first time. Electronic Bulletin boards. The other people on those EBBS were male people. Mostly kids. I used the 'handle' Susan and got me some attention. Those kids were thrilled to talk to an actual girl and, in turn,they taught me probably 50% or more of what I know about computers today. Had my name been something less feminine, I'd probably be a retired shoe salesperson with a rotary dial land line and a diary with a lock and key.
Now Susan a name reserved mostly for old ladies - at least the ones left. After 70 years, I've gotten used to it. It's an ok name.
