Pft. You live with someone who doesn't drink it, so there's a chance you might buy some and not have it disappear while you're at work.
Everyone in my house likes eggnog. We could buy two gallons and I might get a cup before it's gone.
And we never buy that much each season.
CHECK YOUR PRIVILEGE.
I'm going to see about making some, though, with our eggs. Should be nicer than purchased...
