Anonymous Valentine's Day messages

I rather liked 140204 and 140205; unfortunately, 140206 hasn't stepped up to the plate yet.

However, 21406 exists and appears to have the same idea, so if there's someone you want to leave a message for (anonymously or not), go ahead and do so! (And let them know about the community—it's a community this year—so that they'll know to look for messages to them.)
