I think the cool thing about having an unusual name is that you are hard to forget.
Sure it may take a few times for the person to learn how to say it properly but after that it stucks!
Theres only one of me. And even if we hardly talk, a few years down the line someone may say 'oh i was talking to Analesha.. do you know her?!' and they will go 'YES!'.
I quite like it.
