jesus, i guess being humble and showing decent behaviour is lost on some people. ive learnt a long time ago, no matter how good u think you are, there is someone out there that is better, richer, stronger, younger, etc than you. its just the way of the world.
so u have nice cars, so do a lot of people, im sure a lot of the saudi sheiks are secretly bursting with laughter at how "povo" you are. what does it matter? im sure you worked very hard to earn what you have in life, and if you didnt, and you were gifted them via a trust fund, then thats even better, getting something for nothing.
either way, most people in life dont like it when strangers just burst in and start disrespecting people they have never met. and if you think its ok to do that, then good for you
