What are your pet names, who gave them to you, and why. One of my pet names is "hotwheels", given to me by my best friend, shortly after I ended up in a wheelchair. My sister called me "Lijn" when I was a baby, apparently because she couldn't pronounce my full name, or she was just lazy. I have an uncle in the UK who calls me Karl. I think just because he can't pronounce Karlijn and doesn't want to call me Caroline for whatever reason.
