Conversation Analysis:

Dad:       I cant believe we didnt win (.) we was the better team
Brother:  the other team were rubbish/
Dad:                                                 /so were we though
Brother: I dont want to go anymore (3)
Dad:     well Ive paid for your ticket now
Brother: dont care

'Dad' clearly has authority in the situation as he is the only one to break the 'turn-taking' rule. It is clear that the two speakers are close because there is an informal register, words such as 'dont' and 'didnt' are not proper English. The ellipsis shows that the tone is fairly dull and boring, as is supported by lexical choices such as 'rubbish'. The overt purpose is showing that the two speakers are looking to discuss some kind of match or competition.
