We're not supposed to recycle plastic bags, so I turn mine upside down and shake the contents into the recycle bin. This is quite a feat, because I am short, and the top of the bin is a little higher than my shoulders.
Today, as I struggled to shake everything out, I heard/felt a faint jingle.
I'm grateful beyond words for the very timely warning that my keys were tangled in the bag and about to wind up in the dumpster with the rest of the trash. I'm even more grateful that I took heed, despite my big rush to be done and move on.
