Do the RIGHT Thing

it's human nature: you know what's the right and wrong thing to do.
And i expect them to do the right thing.
I expect them to do their homework neatly, I expect them to flush the toilet after use it, I expect them to drink their water whenever they feel thirsty, I expect them not to waste food, I expect them to take care of their own things, I expect them to share among friends, play safe and soft. Be more considerate and independent.
But they(even man) are stubborn and selfish, they do whatever they like but not right.
