bad behaviour-the thinking process

What constitute a bad behaviour?
some consider swearing, spitting, farting, binge drinking, speaking loudly in a restaurant and etc.
some consider not.
Why so?
the thinking process behind govern by a lot of things, but mainly by past experience. You brain recognises that from past experience, you have had a an unpleasant moment with people that behaved like for example: swearing.
Culture play a significant role, as well as the way you were brought up when you are young.
Noone is born with knowledge that they will hate swearing, unless of coz the mom always tell them antenatally.

After all this rambling, so what do I consider a bad behaviour? Being intendedly evil and knowingly taking advantage of someone is an extremely bad behaviour. Cheating is another intoleratable behaviour. I have some pretty bad experience in being taken advantage especially when I trust that person so much. To me you can choose to dislike or like the person, curse them when you are unhappy, beat them up (well, not encouragable) or not befriend with them anymore. Not taking advantage of them coz they are weaker, it is not difference to bullying, especially they have trust on you. It is like a betrayal~lowest of the low!

I can preach whatever I like here, but still I am in the end just human, with feelings and emotions. We make mistakes, some could be ractifiable, but some may not be. I won't pretend that I am great, coz I am not. Ultimately, if you dislike me, you can just tell me in the face (I might cry, but that is beside the point), or even choose to ignore me altogether. But if you have a great heart and willing to forgive me, that will be something that is special in life. Something to look forward to everyday, knowing that there are still people out there that are with big hearts and willing to past this good deed on to someone else...
