Wonder why…

I go to the bins several times a week and something I’ve noticed is there is SO MUCH holiday decor! Christmas, Halloween, Easter…you get the idea! I wonder why. Do people really decorate that much? I get the basic stuff but it’s everything from wall decor, table cloths, window decor, bathroom decor! I’m don’t decorate anymore since my kids are grown but even when they were young I didn’t have huge amounts of this stuff. Thoughts?
