Hello, I would have to go back to my roots. Liverpool v. Everton, this pair of football clubs (soccer) divides families in the city of Liverpool. Two brothers I know were supporters of the teams, one Liverpool the other Everton. Then one Christmas a relative got the sizes of the team kits mixed up. The brothers got the wrong kits, after that they switched allegience to the teams and fight continually about which teeam is best.
Ah! To be in Liverpool on a Derby game day. :)
