Yeah, like lolagrace, I have two hard to spell names. (You wouldn't think Atisket Atasket was THAT hard, but sheesh, some people... )

I will say that in my experience people with genuinely difficult names hardly ever get upset over this, because for us it would be a huge waste of time and energy. It's a waste of energy for anyone unless somehow a misspelling gets onto an official document. You're probably upset because you have been seeing this woman for 5 years and think she should know better by now, since she knows a bunch of other intimate stuff about you.

But consider: she's sick. She's probably not paying as much attention as usual.
