I believe rules are important. Wherever we go, whatever we do, whoever we're with, we form rules. Often without even thinking about it, we decide what kind of behavior we accept, what type of manner that is frowned upon or what actions that are forbidden.
I, personally, have my own set of rules for different types of situations. I think it's important to know what you stand for, what you believe in and what your moral values are. Other people might see things differently and here comes what may cause a conflict.
For rules and regulations to be effective, we often need to meet halfway. It's important to understand that sometimes, when we step onto somebody else's territory, we simply have to play by somebody else's rules. As long as it's all communicated, we can decide if we want to stay or move on to something we find more appropriate in accordance with our own values. The keyword is always respect.
Also, know that breaking the rules and regulations has consequences...
