random thought: guydudebroboss

at what age do people stop saying "can i get that for you bro?" or "how did it go today boss?"  i see this all the time on golf courses when returning from a round and the "cart boy" (i'm okay saying that because i used to be one) greets you with any one of the guy-dude-bro-boss salutations.  man, do i still look that young?  i guess that's a blessing, but i prefer to keep my "dude" references to people i know.
