Inspired my the worst parenting fails thread. Mine is Christmas themed and too light hearted for that thread.
I have a tradition of wrapping on Christmas eve, with each child having their own wrap design.
Last year at 1am Christmas Day, I ran out of wrap before the last present for one child when I still had loads for the other. I panicked and gave the last gift to the wrong child on purpose so I didn't mess up my system.
Luckily they were 2 and 5 and I do stocking fillers last so not too horrific but still.
This year we are doing it differently.
