Quite often shortened to Caz or Caro.
No two Caroline's are the same, the one I know is a complete angel, and another I have heard about is an arrogant and selfish person. Names are just names...
Quite an average one at that.
Young lady: My name is Caroline, what's yours?
Man: My name is Raziel.
Caroline: Your name is so cool, no fair!
Raziel: Yes, quite. :)
guy 2: Dang she's HOT!
guy 2's sister: Thats my best friend.
guy 3: is her name Caroline? She looks like one! Ahhh :).
guy 2's sister: Yes.
