Input: Text: this actually happened a month or so ago, but i just recently started using reddit again. anyway...

i'm ostensibly male. i was at my friend's house. now, we're rather close, and so nudity isn't a big deal around there. so, of course, i'm sitting and watching tv in my underwear, because why not? she was upstairs, taking a nap, and otherwise i was the only one in the house. her husband was at work.

cue, naturally, the doorbell. i scramble to throw on pants, but by the time i've done so, the person was gone. or so i thought.

they normally keep their back door unlocked, for the entry of friends/family. little could i have known, at the door was my friend's *mother*. so, she waltzes right into the room where i (to her, a complete stranger) am standing and quickly throwing on a shirt.

awkward, but it's not the worst thing that's happened to me. but wait, there's more. at this point, the commotion had woken up my friend, who was now coming down the stairs in a bathrobe she had hastily thrown on.
