I started last October, loving it so much. I'm almost at 35 sent which gets me one more card in the rotation. So far all awesome interactions and words apart from the one I got today from Germany. it said "I live here, it has castles" That was it, and it was a picture of a squirrel, not even a castle. So I went to write him a thankyou message and I looked at his profile and he didn't have one, just 525 cards sent and received. I guess we all do it a little differently haha
@Argie I've only sent 3 so far, but should get another in the mail. The sender on this one expressed joy at the process and I agree, its a great way to put some fun and whimsy into a world that could surely use more of those things.
