Your mom was right: Don't talk to strangers.
People are sharing the stories of their most awkward interactions with fellow humans, and they certainly escalate quickly.

Uber driver. I picked a guy up downtown, midday. He was early 20's, red head, tatted out. Extremely nervous, jittery to the point I wasn't sure if he had a condition or was on drugs. He sat in the front. We're driving and he's all over the place, telling me wild stories about how he makes all his money climbing dangerous construction sites around the world and posting videos to youtube. I believed him! Anyways, we are on the highway heading to a nearby town, and he reaches in his backpack, takes out a towel, unwraps and it is suddenly holding a luger pistol. I freeze up and feel cold and hot at the same time. He looks at me with a smile and says "what do you think of my gun?"
I can't tell whether he is being serious or if I am being held up or what, but I try to smile and say "WOW man, that gun is so cool, what is it? I love it, but while we are on the highway, can you put it away?"
