Haha made me think about how my girlfriend runs. She runs normal when she is just running, she just looks a little funny when she plays soccer. She moves her arms mroe side to side rather than up and down when she's playing soccer. It seems like it's because she is always getting ready to change directions at any moment to stay with the play so that probably explains it. But, her friends, brother, and I say she runs like a T-Rex haha. But then again she can run a hell of a lot longer than me and is in infinite better shape that I am. So who am I to say anything!
