My employer hired an intern to work a few hours per week. I wasn't thrilled with having to slow down our work pace for an intern, so he was toning and labeling jacks at first, and started assigning extensions to new telephones as his next "project". Rudimentary stuff.
Turns out his minor is in cybersecurity, though.
He saw me cutting the MAC labels off new switch boxes before discarding them. "Why you doin' that?" So I told him about dumpster diving.
In the switch management system, I showed him the UI and said, "use inference to find out which guest AP is on the east side or west side of the building."
He toned out a possible faulty cable, and said, "its switch port is not lit. Can I disconnect it?" I said, "Sure! As long as you're certain you won't disconnect their cube partner." He double-checked the tone again.
When I asked the company which recently did our VA for their data deletion strategy, the intern was aware of the correspondence and asked why that matters. I told him that they now possess data about our network, architecture and infrastructure, and that we need reasonable assurance that this sensitive information is destroyed. This led to a topic about banners, their usefulness to infiltrators -- and eventually led to a talk about NMAP.
He'd never seen NMAP before, and fell in love with it, apparently. And he's starting to grow on me.

A claim is as good as its veracity.
