If they usually go by a short form of the name, which one do they use? Cathy, Kate, something else?
How old (roughly) are they?
Note: I have the statistics on the name from the Social Security webpage, but I was hoping for some more personal insight.
EDIT: Wow, you guys are fast! Okay, it looks like there's a lot of them about, and most of the younger ones are a variation on Katie or Kat, while the older ones tend to be K/Cathy or Kitty. Very interesting, and just the kind of information I was looking for. Thank you all so much! : D
