One of the things I'm most grateful for is my mom's decision to move back in with her parents following a messy divorce when I was just 5 years old. The six years I spent living with my grandparents were among the best of my life - I had a great childhood and have a ton of fond memories. Unfortunately, I may have also picked up a few bad habits along the way.
My grandparents lived through the Great Depression, and like so many in their generation, they got into the habit of not throwing anything away. They weren't hoarders or anything, but they did hang on to stuff they thought might be useful in the future - plastic containers that could substitute for Tupperware, paper grocery bags, twist ties from loaves of bread and much, much more.
