I have a Legend of Zelda coffee mug at work, and it’s been there for some time. Most co-workers don’t bother to comment on it, though I’ve had a few remark “That’s a big mug” or ponder “How do you drink from that?” when they see it.
Recently I’ve had two co-workers actually say “Oh, so I guess you like Zelda, huh?” to which I cheerfully agree, because obviously (but I would love to have an ironic coffee mug). They both then followed up with “Is that still a thing?” To which I utter a weak affirmation and then hang my head and realize that I’ll always be alone here.
