it hurts

Sometimes they are people who thinks that they are so smart that they know everything there is to know about and it doesn't occur to them to even bother what others have to say. It makes me so sick to my stomach and it also hurts deeply. I know i'm not 'one of them', i'm sorry that i came from a third world country unlike you people who were born here which makes you a lot more better than others. I seriously thought i came here to improve my lifestyle and to add on knowledge so that i could change the quality of life, but factors such as 'them' makes it hard to improve and to even survive in this gruesome world.
The other thing that disturbs me is that once a person branded an impression on you that you are not that smart, then tend to try and avoid you. Maybe even think that you are too 'low' for them.
It really does show prominently that whatever comes out from your mouth is pure rubbish and would never help them in a way. Hell with them, can't they give a person a second chance or doesn't it ever occur to them to help that person to improve in every single way they could help?
*This doesn't apply to all, but it does apply to all anus holes*
Even if that person isn't as smart at you, does it really hurt your ears to listen to what they have to say?
