Input: Text: today, my neighor has been practically hanging on my doorbell all. day. long. a couple days ago, i found her cat, which was hiding under the stairs, and returned it. since then, she's been ringing the doorbell every freaking thirty minutes, asking for help with something totally inane. so there's the backstory. about fifteen minutes ago (right on time, dammit), my doorbell rang. i'd had enough and shouted that, as well as several less-than-polite phrases. i yanked open to door to tell her to leave me alone, but instead found a youngish mormon missionary standing there, eyes all welled up. he took one look at me and ran. poor thing. so, today i accidentally cussed out a missionary and made him cry. i'm sorry, missionary, wherever you are. i'm a witch, but i'm usually nice, i promise.

TIFU by cussing out a missionary.
