As Dad was packing he proudly showed me his ziploc baggie of six little freebie shampoo bottles from hotels. They are from the Choice Hotel chain in a design they retired probably a decade or more ago. He holds them up, as if they are a burden he just can't shake. "They're so close to the end that I have to put a little water in there and shake them up to get the shampoo out."
No. You don't.
Do it when you're in the shower finishing the last mobile bit, sure. SURE. I'm not a monster, I rinse out bottles of stuff like shampoo too. But to have six of them, six that you hauled across multiple states on a one week trip to visit family? Why?? Why are there six?? Why are there six that I know about, and how many more are there?!?
