I think this is not about nationality, race or even age...

It doesn't matter where one sets his/her foot on. No matter how good MOST people around are, He/she will find others who will tick him/her off.

That is nature. Vicious as it is, it is nature. No matter how much good is done, one can mostly remember the mistakes made. That is how humanity view each other.
We look for what is bad disregarding the good. And we only notice the good things, when the time is too late.

if it cannot find a way, It will make a way"
