First off, your boyfriend was right, the base 64 encoded message was a very nice touch : ) (When I first saw it, I thought you sent me an EdDSA key and was a bit confused :V)
Thank you very much for all of the gifts! The post was a while ago, but I had indeed not resolved my sealing supplies situation yet. And stroopwafles! I love them! (I basically subsisted of them when I visited Amsterdam half a decade ago.) I also didn't actually have a water bottle currently, so that's quite convenient as well : )
