Real-Life Encounter in Boston T Elevator

[I run into the elevator just as it's closing. Middle-Aged Lady (pictured above) is only other person in elevator, facing away from me]

[Middle-Aged Lady lets out a long, relaxed fart. One that seems like it's been saved up all day]

[Middle-Aged Lady turns around to notice that I'm there]

Middle-Aged Lady: Jesus Christ! You snuck in here silently! You're supposed to make a noise, make other people aware of your presence.

Me (suppressing laughter): Oh, sorry

Middle-Aged Lady: You're the one who should be embarrassed, not me. You snuck up on me - that's just not right.

(beat)

Middle-Aged Lady: I'm not embarrassed. You're sneaky.

[Elevator doors open. Middle-Aged Lady runs out into the Boston night]
