In gym class someone running in my direction while i was doing a front flip and when I stood up, bam their shoulder smashed me right head on with my nose. don't ask me how that worked.
When i bang my knee against something thye wrong way, it starts to throb(throbing pain sucks the worst) and over nite my leg is either straight out or bent in and so in the morning when i try to move it it is like someone taking a sledge hammer to my knee.*The Pain*
