I'm not talking about having your heart ripped out by some tart. I am talking about proper, physical pain.
When I was 6/7, I was running in the school yard and, as is the norm, some girl wasn't watching where she was going and ran in to me. Her fod smacked my eye. I cried...she didn't. I ended up with the biggest shiner you've ever seen in your life.
I also got punched in the stomach by some girl, also in school, when I was about 9/10. I was much braver this time and didn't cry...I just rolled round on the floor winded.
