I got my "Have a Nice Day" mug as a Secret Santa gift from a co-worker at my first job after college. Yes, it was meant ironically. I've never been much of a morning person, and certainly less so then than I am now.
This mug has served me caffeine, and served it well, for nearly 28 years. Until this morning, when being rinsed in the bathroom sink it slipped from hands and shattered on the tiled floor.
Fare thee well, old friend. And have a nice eternity.
