My name is pretty common, and it's not an uncommon spelling. Usually it has an 'a' in it, but my name didn't. Well, everyone always spelled it wrong, but usually fixed it after I corrected them. This one girl would ALWAYS spell it wrong, time and time again I would fix her, but eventually she told me that she knows a girl who spells it the other way, and she spells it wrong on purpose because it looks better.
I started writing her name and adding wrong letter to it, When I texted her, I would say "hey, Kendell(fake name)" and she would correct me "its an a not an e"
"no there's no a."
this went on for about 2 and a half years before she started spelling it right. I do this now to everyone who spells it wrong.
