Whenever I go bowling the computer only has room for "Christ", which is a bit weird. I love my name and wouldn't change it for the world.
I know 4 Christina's except one spells it with a K and not a C.
Since I was born in the 70's, there are a lot of people my age with similar names, which meant that I was sometimes "Little Kris" or Chrissy G. I don't really remember having other girls in my classes with my name, unlike the names Jennifer, Ashley, Sara...
I remember having 1 maybe 2 girls named Christina also up until middle and high school where I met more.
All of them had the middle name Marie which I see now was/is a common combination used with Christina. I have always preferred Christina to shorter ones because I just don't feel like a Chrissy or a Tina.
