Words Between The Button Pushers

[I am already in the elevator when SHE enters.]

Me: “Where ya goin’?”
Her: “Seventh floor, but I’ll pre-“

[I press the button for the seventh floor.]

Me: “No problem, I got it.”

[She stares at me, seemingly annoyed, then the doors to the elevator close. A few seconds later-]

Her: “I said I was going to press it.”
Me: “Excuse me?”
Her: “The button. For the seventh floor. I said I was going to press it.”
Me: “Ok.”
Her: “But YOU pressed it.”
Me: “I was doing you a favor.”
Her: “Well the next time doing favors for someone involves pressing an elevator button after someone else expresses their desire to press the button themselves, maybe you should leave well enough alone.”
Me: “You’re kidding, right?”
Her: “I don’t kid about someone pushing my buttons.”
