Ignore is the biggest contempt

Its great to bear their attack. Its not necessary to countershow them any contempt. Their malicious behaves will automatically re-attack them. Its natures property. Stay fine.

People who criticize and attack others do so because they depend on others to make themselves happy. We cannot control the behavior of others and it is ridiculous to expect them to behave in ways that satisfies us. Indeed, the best way to handle criticisms and personal attacks is to just ignore them and maybe take pity on those who cannot handle the responsibility of their own happiness. :)

Absolutely. Ignore people who back stab or gossip behind your back. The more you show them that you are affected, the more they rejoice. But once you show them you are not affected- they will stop and get annoyed. Therefore, why give them satisfaction when you can kill them by giving the dose of their own medicine.

That is right! I am a quiet person by nature. I hate having debates or arguments. As much as possible I try to be cool with everyone. When there would be someone who wants to annoy me, I just do not mind him/her that much. My silence could irritate him back, right? So what waste my time and energy for some worthless person?

I agree with you. Often times trying to talk about things when someone doesn't want to listen or have an open mind is a waste of our time. It usually gets people no where because no one is willing to change their mind.
