... refilling my mug with water, I dropped it and it shattered on the floor.
This is notable because the mug in question was unique and irreplaceable: it was one of the little promo freebies I got, waaaay back in the early '90s, from Wizards of the Coast and had the first print of their new logo (dark background with a shooting star over the "Wizards"). Wizards saved my life, so to speak, more than once; my early investment of a small amount of time paid huge dividends to me over the years, and I will always remember the company fondly (even though it is now a shadow of what it was, a piece of a larger corporation that doesn't really understand the relevant industry).
