It ended up being three hours.
Apparently I needed it more than I thought. Anyway, turns out that breakfast was a mistake, but I didn't realize it until late afternoon. See, when I saw those eggs in the fridge, I thought to myself, "Gosh, those are getting old, better eat them before they go bad." Except I'd already had that thought a few days earlier, and planned a meal for last night that would use up the eggs. Which I now no longer possessed.
So I had to call the egg lady, who couldn't meet me at her house until 5:30, and after slogging through traffic to get home I decided I didn't have time to cook the planned meal after all. So we had leftover ribs, which the kids were perfectly happy with. The egg-utilizing meal will be tonight instead.
Oh, and breakfast this morning is granny smith apples with cashew butter. So freaking good. I feel bad eating up all the kids' cashew butter, but tomorrow's the weekend and Mr. Clod can make some more.
