Cheat? If you buy yourself something...it's not a gift. It's just a purchase.
Even though "I" bought a pile of computer parts for a new build, my wife has insisted that I wait for Christmas to open the boxes and start the "construction." I don't like that...but I will obey.
However, "she" bought herself a pile of clothes...and I'm insisting that she not open them until Christmas either...she DEFINITELY doesn't like that...

But, she has a birthday before Christmas...so I MIGHT let her have one or two things from the pile...maybe.
