I know gift wrap and bows are on sale. They'll still be on sale in a couple of day...for even less! You've earned a few minutes of rest. Take them.
I know you got that sweater that doesn't fit. You don't want to be standing in those long lines today. The customer service desk will still be open when you get there. It doesn't have to be today.
Today is for you. Enjoy a few moments' respite and breathe. If anyone gives you grief about it...tell them I said so!!
