Be careful there, my mother went and told me about how careful you have to be on your actions. Be aware of your environment and what you do. don't want to disrespect anybody or offend them because what we see as a pat on the head to a younger child, they see as some very bad gesture.
Thanks for the warning Jab, I have been researching faux pas in Bali just to make sure I don't do anything wrong :S
Pointing at people, exchanging goods with your left hand, being drunk in public are all very offensive.
