[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.
Middle-Aged Lady: I'm not embarrassed. You're sneaky.
[Elevator doors open. Middle-Aged Lady runs out into the Boston night]
