"Hey, love your music man!"
"Huh? My music?"
"Dude, you totally resemble Robert Smith from The Cure!"

"Ooh hahaha, thanks."
"So, what I actually approached you for, we've had a call that reported a shady looking person carrying a knife in this area. You seem fine, but just double checking because, well, we see weird shit sometimes and don't want to be negligent."
"Aha okay, fair enough. Well these look like knives perhaps but they are actually professional gardening tools. I can show you my masterpiece actually."

"So cool man, should get my ass into nature more too. Sorry for the trouble and thanks for your time and understanding. Have a good one."
"Cheers, see you around."
