Respect?

most of you probably know this quotation

"treat people the way you want to be treated"

What if.........

You have tried to be nice to someone but on the other hand they disrespect you? then why should you try to be nice to that kind of people?

I am not saying that you have to disrespect that kind of people too....

probably the best way is just ignore that kind of people...

those people don't deserve any attention.......

yeah probably.........
