DH is Corey, not Cory... HIS relatives still don't spell it correctly..
DS is Erich, not Eric... We get that one a lot too; most recently on DS report card- written by his teacher!

It was in a sentence about slowing down on work, and DS making mistakes because he goes too fast.. DH was almost on the floor with that one, DS just rolled his eyes.
I am Cindy, not Cindi, not Cyndi.. I don't get too many screw ups.
DD just goes by her nickname Tia. very simple, very easy.. don't even try spelling her name-
Christiana.. she gets Christina every time she goes to the doctor or dentist.. and I sit in the waiting room, looking around to make sure there ISN'T a Christina before we get up!
