Trick or Treat Exchange letter

Hello, Trick-or-Treat creator! Thank you so much for making something for me. This is my first time in this exchange, and I have no idea what to expect, so I'm looking forward to the surprise!

I'm going to spitball some things to give you an idea of what I like, and I hope you can use them as a jumping-off point. Don't feel too leashed to anything I say if you're not feeling it.
