Take a long walk. Be as far away from the person and the situation as possible.Try to talk to other people about other things.Then come back when you're not as pissed.

My former students used to say that I'm very pasensyosa and I don't get pissed easily kahit sobrang kulit sila. When I'm about to get pissed I walk away. If the person who's pissing me off is doing it through chat I go offline. Through txt I turn my fone off.

It just gets hard when the other person can't seem to get the message and would keep on pushing you up against the wall even when you come back from a long walk etc. or from going offline that's when it gets hard when they keep on pushing your buttons...

but as much as possible kung kaya pagpasensyahan isipin mo na lang that the person is not worth any wrinkle on your face...write a letter to get it all out of your system.
