My dad called me Chrissy from the get-go. I HATE that nickname. I have only ever had one other person call me that but it didn't bother me. My brothers used to call me Pi**y Chrissy until my mom made them stop. When I lived with my grandparents, Grammy would call me Joanne (my mom's name) and I would answer; otherwise she'd run through a whole lotta names before she got to mine. I have always gone by Chris but I do tell everyone that if you must use my formal, given name it is Christina with an "a" on the end and not an "e". Ex-FIL called me Christy. I receive a lot of mail addressed to Mr Chris Smith which ususally makes me laugh.
