Absolutely true.

However, that doesn't mean you can erase your old name from other people's minds and mouths.

I still have people that call me by my middle name.

I first started using, and requesting that it be used by others, my first name innnnn... . Fuck. I think it was 86? +/- a year, in that range. So, you know, fictional Gaylord from this urban myth is likely to run into similar, and maybe worse because at least I was using a name I was assigned by my parents, which reduced friction a ton both in the family and at school.

But that was forty fucking years ago, and the majority of my family still use my middle name. There were a couple of classmates that took a year or so to switch, and a couple of assholes that refused to and even tried to weaponize it.

And neither of my names is as culturally awkward as Gaylord.

Folks reading this far that might have someone in their life that wants to be called something other than what you're used to. Be a bro, give them that respect. They'll value you for it.
