Sure you can piss off any girl if you muck around, come home late (or not at all), don’t reply to her text message or whatever but the difference is western women just seem to wait for reasons to get mad at you and they are also a lot more resentful than any Thai girl will ever be. Small things are big things for western women and so you will never meet a Thai girl that gets angry because you left the toilet seat up. Even if you really make a Thai girl angry and that doesn’t happen much at all she will forgive you anything, even having banged her best friend.
