why do you assume to put "rules" on an activity you obviously don't participate in and know nothing about?
why do you even call yourself an "expert " in this field when its clearly obvious you're not?
"Few rules to follow" - no there aren't, stick your rules up you arse! "Premarital relationships" - what the fuck has that got to do with skateboarding ?
The only rule with skateboarding is : Have Fun.
