Are you going to do anything to prevent this unusual & abnormal situation from recurring?
If so, congratulations on better planning.
If not, then Good Luck & Merry Christmas.
I have considered putting it on a chain around her neck.
Or just leaving the key with a stranger in the next car - you know just in case. Lol
Actually, I have more important things to stress over other than one off event preparations.
I do thank you for the good luck wishes and I wish for you to have a Merry Christmas also.
PS. But now that you do mention it, I might have a spare key behind the license plate, hmm or was that the old truck. Not sure now, might have to check it out some day.
