in a fight never through a first punch for leagle reasons like for example they are going to ask who started the fight all you have to say is that i didnt through a first punch but also never talk during a fight just beat him/her up and thats all dont stress is unless u started it .
biting you tongue hurts when it not on purpose because your body is ready to take the impact of you teeth and when its not on purpose, you tongue is soft and easy to cut through
