A few days ago, I had a teenage boy come to the door selling knives!

We're talking about big huge kitchen knives. Even though he wasn't brandishing them at the door (the knives were in a briefcase), that was still unsettling.
Luckily I recognized the boy as one of my little brother's classmates from school, so I didn't call the cops immediately. But I gave him a talking to about how people in my neighborhood will most definitely be calling the cops on him. He said he couldn't find a regular summer job doing life guarding or busing tables, and this was the only gig he could find. Sad, but still...
