1) Speak with a Northern Accent. (If you don't have one - LEARN how to speak it - make sure if you are interviewed everyone can say all city fans live in Manchester the fact that northerners know the different dialects is immaterial to everyone else we sound the same)
2) Be born within the old boundaries of Manchester or at the very least make sure you are from Gods only County Lancashire. If you were born elsewhere - Lie.
3) Have been to at least one game at Maine Road (heritage) and Etihad (on going commitment) For those too young who couldn't now go to MR, make the pilgrimage so you know where it was.
4) Away at York is essential even if you didn't go. Attend at least one away match to compensate.
5) Make sure the colour red is nowhere in your life, it doesn't exist.
6) We are not arrogant even if you think we will piss all over the opposition still use the word "IF" we beat.......... Be able to laugh at yourself as a city fan and take flack, be magnaminous in victory even if you find it difficult, except on derby day when it is permissible to take piss remorselessly if we win.
7) Know the term Typical City and what it means, it isn't dead yet, it may be sleeping for a while but it will never go away.
8) It is notright to own half half scarves with teams from prem league, foreign expeditions this restriction may be relaxed. Definitely out though is halfy halfy shirts.
9) You cannot have another team you may have a softspot for another side.
10) If you cut yourself shaving, or by accident, don't forget your blood is blue, it may look red but just accept you are colourblind in this respect.
