No one has ever suggested it. I think one person might have suggested Mim, and another suggested
Mimi. I actually wouldn't mind
Mimi, however that's what the grandkids call my mom.
Even with Miri, Mim or
Mimi they aren't going to be the first thing that pops into a person's mind. It's not like
Tim,
Liz,
Jen where the nickname shows itself in the first syllable.
