Nicknames you have; why do you have them
Nothing terribly interesting for the most part. Just variations of my name.
Mom, Mummy, Mommy, Mother (the last three occasionally used with sarcasm); Jenny, Jen, Genie and Nia (only my hubby gets to use that one).
When I was much younger for a brief time I was called “Happy.” I started it based on a Michael Jackson song. Oh, and my father used to call me “Skinny Minnie” when I was a preteen.
