No one can seem to pronounce my name either, it is Eva, Like the name Eve-ah. I get called eva, ava, and sometimes even eve, evie, ev-ie, lots of strange things. It's not even that uncommon!
My real pet peave though is when people stick extra apostraphies in places they DON'T belong, like, "In the 1970's..." or, "My sister knows her ABC's..."
