Football teams???/????

"I will never forget i went to some random Darlington V Middlesborough friendly when i lived up north and it was a good laugh lots of chanting and stuff and it was a good day. Then it got to time to leave and the gates opened as we got out down the street.... well.......thats when the bottles started flying haha Baring in mind i must of been about 11-12 i was paping my self as all these grown men are fighting and brawling accross the street. But this was a friendly game now i know i dont know much about football but surely a friendly means its just a training game and doesnt even count to the clubs scoring. So why fight about it? lol was still very funny to watch but was abit worrying at the time. That also made me mam not let me go to big things like that with my mates till i got a little older. Damn lol haha "
