Ok, so, It's not possible to write down everything in the rule-book. Because human stupidity is infinite. It's not too hard observe and decide, what is bad, what is a serious crime and what is not. From human instinct, deep down you always know that, it's not too hard to differentiate between right and wrong. Sometimes you have to make decisions and take action on the spot, without the comfort of consulting or taking advice from your seniors or someone, then you will be guided by your own instinct. 😀☕🎈👍.
