Do you know much about mechanical things? I surely don’t! I wouldn’t know if something needed a hydraulic hose, for example, or not. Now I do know a little about cars, not much, but a little bit. If my husband is talking to me about something on our van, I would probably know what he was talking about. I probably wouldn’t know how to fix it, though, because that’s his department! But at least I’d have an idea what he was talking about.
