sending letters in the mail is such a good idea for so many reasons. (and a bad idea for a few reasons) mostly i love it because the anticipation of the recipient getting the treasure lasts so much longer when it's sent in the mail. and then when they get it, it's something physical, it's multi-sensory! they can pick it up, and open it, and hold it. kind of funny how novel all of this sounds. i really wish it were still the norm. but that's just me. i have an old soul.
