Hello,
With gendered names, I'm fine with variations of rebecca or robert now. Most peoples use derivatives of Robert, of course, because they don't know any better.
I really prefer the non-gendered name. I am considering changing my name to Rebis, but being the slothful baboon that I am, it will not happen soon. Maybe 20 minutes before I die or something.
I think I'd also be okay with Nic's wife calling me Nick. But I'll stick with Rebis.
Have fun, not babies,
Rebis
