The first time I saw a group of Britons jumping and screaming without shirts outside a pub I really got scared, but now I have got used to seeing it and it doesn't scare me anymore because I know that when this happens it is because there's a Football match.
Before I saw this kinds of action in London I didn't kow that Britons were so fanatical about football as brazilians.
I used to think that just brazilian people were crazy about football but now I know that Britons are so. Different from what a lot of people probably think in Brazil, and I used to think as well, when watching a football match they really scream and jump instead of being calm and quiet, they are as crazy as brazilians.
During the football they lose the calm British way of being and turn into ordinary football fanatics just like brazilians are.
