AES: One letter and one flat surprise #2

This swap seemed to be popular the first time, so here we are with a second round!

Write a letter to your partner that has at least two sheets written on both sides. Along with the letter, send a flat surprise that fits inside the envelope: a sheet of stickers, a bookmark, a postcard, or whatever you prefer and you think your partner might like.

Please, keep in mind:

The size of the sheets should be at least A5. Don't send a small note paper and call it a letter. Instead try to write a nice long letter that your partner will enjoy reading :) Write somewhere in the letter the name of the swap, so your partner knows where to rate.

Replying to the letter is of course optional, but it's always a nice surprise :)
