Not sure if I would have used a different name - although even though Kath is short for Kathleen (my middle name) - I for some reason get pissed when people call me Kathy. I don't know why.... lol
The funniest thing is when working with new clients or companies - I've had hotel/airline reservations made for me in the name of Kath Blackwell only to have to explain awkwardly that while I'm "her" that's not "me".
I guess maybe I would have just picked a non-name name to avoid the confusion.
