Why I can't rap.

I was just in the shower pondering various things when I suddenly came to realise the reason why I can't rap. I realised that in order to be able to rap you have to be deeply ingrained in a specific culture, to understand it enough to be able to rap about it. Don't get me wrong this isn't me lamenting over my failure to break into a career in rap, on the contrary I think it's one of my best attributes. For example a rapper I heard once rapped 'mr politician on your television..something something.. all those lies' obviously he's from a politically left culture and understands it well enough to put it to words coherently and sincerely. But has he ever met a politician? Is he talking about all politicians? does he really understand the politician? I'd like to believe I'm in a better position to do so and I'm glad about that. but alas I myself have nothing to rap about. You could say I could rap about being a Barista but I don't have a big beard, arms covered in tattoos, I can make good coffee but I'm not culturally ingrained in it. I spread myself culturally thin, take that as you will but I thinks it's a positive thing. Rappers you could say are on the inside reaching out but I like to be on the outside reaching in, giving them all a high five perhaps.
