Random Stranger Danger

(I’m in an underground station, waiting for the next train. A young woman is sitting on the steps, talking on her mobile in hushed tones. A short distance away, an old man is standing alone. They’re clearly strangers to each other. The old man seems to be mumbling to himself.)

Old Man: *suddenly speaking loudly, pointing at the tracks with his cane* “Be careful, that’s very dangerous!” *goes back to mumbling*

(A few seconds later.)

Young Woman: *hangs up the phone, then yells in frustration* “SHE’S SUCH A B****!”

Old Man: *not missing a beat or turning his head* “I told you so.”

(The young woman looked at him confusedly for a moment, and then started giggling with everyone else.)
