"Dude, check out my secondhand kite gear that's for sale."

"Wow man, your ad says it suits a beginner."

"Right dude, it's perfect for a newbie."

"But man, should you really be selling this stuff to a newbie?"

"Newbie, expert, I'm not too fussy dude."

"But man, it would be immoral to sell it to a newbie who's had no lessons."

"That's strictly correct. No proof of lessons, no sale. I need to be prudent, dude."

"You're a righteous fellow, man."

"You too, dude."

"Whatever man. Anyway, it's easy selling stuff when it's windy."

"I have a slightly different selling policy in the off-season, dude."

"Me too, man."
