USPS version of TPing Houses

I know there are swaps for Trick or Treating - it's been done, I get it. I don't care. I like it! This time, though, let's just send tricks and see what we get.

1 postcard to each of your partners, make sure you read their profile to get a feel for what they don't like.

Handmade, store bought, naked or in an envelope. You choose!

Let's not be too offensive or anything, I mean dead kittens for me wouldn't be cool and may get me beat up by my mailman
