Celebrating Christmas in a park (maybe under a tarp)

We will celebrate Christmas. If you show up, you will also celebrate Christmas.

What to bring: 1 wrapped present (value around 5eur, max 10 I'd say, so nobody get's spoiled/is disappointed).

If it rains (which it very well might, according to Mr Google) I got a big tarp, which we can put on top of ourselves. It's big but not infinitely big. I feel like it would fit max 15 people, so I suggest being on time so you can get a spot 🙃

Also: Don't forget the wrapped present.
It's essential for what we will do.

Optional, but highly encouraged (possibly a factor in getting a spot under the tarp): Christmasy cookies, Christmasy clothes, Christmasy decoration.

PS: wrapped present
