Worst name thing was the summer school class where I had a “Kiyanna”, pronounced “KEY-yan-nah”, and a “Tyanna”, pronounced TIE-anna.
They got really upset if I mispronounced their names, too.
I also had an Ixmucane one year. (It’s Maya, in case you were wondering. Pronounced “ISH-moo-ka-neh”. She went by “Ix”.)
