I’m a pretty easy going guy and have very few rules in life (the main rule being that there aren’t many rules and what few rules exist are generally subject to change at any moment). However one rule should always be implemented; if you are an adult male you should not wear any type of ball cap backwards unless you are catching a baseball/softball game (rally cap is fine here), riding a motorbike without a helmet (a bicycle on a windy day is okay too) or looking through the view-finder of a camera. And the older you are the worse it is.
