Be thankful for the things that you already have. There are people all over the place who don't have food to eat, a bed to sleep in, or a home to spend time with friends and family in. There are many who are struggling just to survive another day. If that isn't you, then you should be thankful. I know I am. We have food, shelter, clothing, and lots of stuff that we just wanted at some point. I'm not condemning people having stuff. I am condemning people who want to horde as many material goods as they can without giving another thought to other people. Shame on you.
So have some stuff, but be thankful for all ot it. Take time to enjoy the people that you have in your life, not just the things. And if you have the luxury of having stuff, take time out to think about others and help them out a little. Donate some food to the local food pantry. Buy a toy for toys for tots. Do without one or two things so that someone else might have one or two things. Remember why we should be thankful this time of year. And it's not for the sales everywhere.
