The perfect Christmas is you, your significant other, and NO ONE ELSE.
So you and your mate have decided to just lay low for Christmas this year. No family, no friends, just 48 hours of pure yuletide bliss.
Decorate your tree with couple-y ornaments.
Try putting your initials on stuff, hanging photos, or painting ornaments with your faces on them. Yes, this is borderline cheesy. But guess what? NO ONE'S GONNA SEE IT BUT YOU.
