We have two sets of car keys: the bear keyring one, and the "Ian keyring" set.
Two days ago my good lady asked if I had seen the bear. No I replied: "It will be around somewhere." However, after a quick look, we couldn't find it. Nevermind eh, it will turn up.
This morning the need to head out in the car arose: we had run out of prawns for the cats breakfast and were running low on beef for the same purpose along with a few heavy bits like cat litter and bottles of pop. No worries, I'll just drive down to the shops using the "Ian" set.
Can I find the "Ian" keyring? Nope; nor the already missing bear set! I have checked EVERYWHERE I can think of but they are still missing. Sigh.
Looks like I will have to cook some chicken for the cats breakfast instead. They won't be happy.
