The ballast on the overhead kitchen light died. On Christmas Day.
So, until Lowe's or Home Depot open early Saturday, we swapped in a basic bedroom closet type fixture...
It pays to keep some basic fix-it or replacement parts on hand. Just in case.
Update: Neglected to mention I'm counting my blessings for having a sump pump standing by when rain began filling the crawlspace next to our basement with water. I had uninstalled the pump seven or eight years ago because the crawlspace "never" got wet. Rising water in the previously dry sump barrel necessitated a quick pump re-installation on Christmas Eve.
