There are probably more than ten similarities but these are the ones I find excruciatingly funny and probably ironic and no, you can't argue with me about it.
1) Everyone has a bloody pet name. Mostly an irritating one that's not remotely connected to their real name. And since it seems there are more Asians on the streets of London than white folk, statistically speaking, you know I'm right
2) The weather sucks. For various reasons but suck it does, at such a level that one immediately wants to one's their knickers and run up and down the street exclaiming 'it's the end of the world!'
3) Curry pervades. It doesn't matter what colour or intensity or flavour. Curry is omnipresent, whether at an Indian store or a fancy restaurant or the stain on your shirt you're trying to hide. Curry curry, everywhere. And no, I do not care for it.
4) Politicians will make long speeches, clever speeches, democratic speeches and then do bugger all about it while the common man lights candles and marches about for whatever latest cause there is.
5) The much-touted heart of either country has very little heart and a very troubled soul and you will be pickpocketed at the most inconvenient time.
6) There is always some 'breaking news' that often ends up being about someone's skirt blowing in the wind a la Marilyn Monroe or some really rich bastard who inaugurates yet another Louis Vuitton store.
7) Everybody has a scheme. Get rich, get laid, get elected, get back, get out, get more, get get get. No giving. You, with the self-righteous conscience, shut up.
8) Everyone's looking over their shoulder. Whether it's a fundamentalist mob, teenage punks, rapists, terrorists or spycams, people carry their fears around like a bad odour.
9) Bankers, lawyers and doctors are always rich and always out to get richer at your expense. Even the good ones.
10) Everyone dreams of their 15 minutes of fame and a lot of them achieve it by being nothing but famous for being famous. And people are still fascinated by the ultimate fame- the monarchy.
I know this should make me smile and feel more at home in either city and it does, in many ways. It just makes me realise rather sharply that no matter what, it's not people who shape a city. It's a city that shapes people.
