I've had long conversations with my meatspace friends about this, and I do the same thing with them. I prefer subtle implication, to the point of near-invisibility, because it feels more 'sincere' than explicit statements. But such subtle implication is often missed even by people who've known me my entire adult life and are receiving my interactions in meatspace, where subtlety is more apparent.
IT JUST FEELS SO MUCH MORE NATURAL TO NOT SAY IT AND HOPE PEOPLE PICK UP ON IT ANYWAY
