For Shopping and More
'Twas the night before Christmas.
Last Minute Day is a not-so-subtle reminder (as if you needed one) that tomorrow is Christmas, and you need to get your shopping done posthaste.
It's also a reminder that you need to clean the house, prepare the food, and do whatever else it is that you do before the guests - who may or may not be relatives - arrive.
In some locations and in some years, this may include shoveling snow so that there is room for all the cars to park.
If you have relatives that are already on the premises, you may enlist their aid in performing any or all of these tasks.
Some of you probably will not get everything done at the last minute. All I can offer you is shame. You should have started earlier, and you know it. Get your act together before next year.
Merry Christmas.
