Are there any rules in this world for everything

Are there any rules to be a good friend
Are there any rules to be a good brother
Are there rules to be a good son
Are there any rulus to be a good uncle
Are there any rules to be human

If there are rules to life then I can't find them
If there are any rules to all I still haven't found them

It is not aff a lack off trying I looked every where but I can't find them
I looked in every corner, in every place but there are non written down

So I can only follow my rules and hope that it will be good enough to be a good person
