I did -- I was a teenager at the time. A group gave a "living Christmas" tour at a Victorian-era local mansion.

At first the assignment they gave me was to be changing into my Christmas outfit behind a screen. I really did not like the sound of that but I thought okay, I'm technically clothed anyway and just miming putting on or buttoning up a gown all day. I'm behind something. No one can see.

Then I'd now guess inevitably, an older gentleman taking the tour stepped into the room and peered behind the screen. Yep. Nope.

Luckily I had amended the assignment by then to keep the gown on and just mime messing with buttons or sleeves, etc. Still. Creepy.

So after that group had gone through, I went to the coordinator and told her what happened. I suggested from then on I write Christmas cards or something. And that's how I spent the rest of the day. At a Victorian 'secretary' desk writing fake Christmas cards.

Ever volunteer at Christmas time?
