I had some boxes I needed to get to a friend. She lives within walking distance, but I had it stuck in my mind that I'd need a car to take the boxes to her.
Yesterday we were planning to walk over to give her some papers. I thought to myself "Hmmm...would the boxes fit in the boys' wagon?" The answer was actually "No", but I then realized that I could use the hand cart. The 3 file boxes stacked nicely, and they weren't all that heavy (I was decluttering some of my cake baking paraphenalia and she is a baker).
Easy! A small car trip avoided, another use for the hand cart discovered. It was a nice walk, too.
