My husband is always fixing or tweaking something around the house, and I usually have no idea what he’s working on.  Last Saturday when I was on my way to the grocery store he asked me to pick up a flow meter. I had no idea what that meant, but I knew I would get some help at the hardware store. I asked the first salesperson I saw, and she led me to to the right aisle. There were so many different types to pick from, and I did not know which one was right because I didn’t know what he was working on.
