Never really thought about it mate ,its kind of instinctive and comes easy
For instance I was in a cab last week coming back from town and the the driver uttered those words any passenger dreads "Are you a blue or a red mate" now the very act of placing Blue in front of red led me to assume I was in the company of a Bitter and so the challenge was accepted " Ive nothing against Liverpool mate,I think you are as Sh*t as us and neither of us are good enough and I don't rate your manager"my considered reply was "see that's what galls me about you Bitterz you're twisted enough to bracket a club that is clearly progressing with a world class manager with a club that is a level below *****, I mean you have a manager you clearly don't want at the club,but your fan base is willing to sit there with their 'half season tickets' and persist with his methods because you have had the fight sucked out of you by countless years of failure. Drivers reply "Are you watching the boxing tomorrow night "
