"Spring Cleaning" the "Wine Cellar" is exactly what we called it (what we did over the weekend for fun(?)) but the phrase is a perfect example of how we adopt certain words and use them without regard for accuracy!
First of all, it is November, there is nothing "Spring" about this time of year. But any purging project, regardless of the season, I call it "spring cleaning;" pretty much any job that involves loads for the DI/Goodwill.
Secondly, when we moved into this home the real estate agent called a storage room off the playroom the "wine cellar." Thus, it became "the wine cellar." We store storage in the garage and storage in the wine cellar but we don't technically have a "storage room" per se. It's all a little ironic since we don't even drink wine; most home buyers would probably "christen" the room with a new name that held some logic for them. Maybe we are just lazy; but we all call it the wine cellar. Which must make people wonder why the Bishop's family needs a wine cellar.
To add further irony, our wine cellar isn't remotely like a true wine cellar! This wine cellar is just a basic unfinished room; dark, stark, and cold. And you might wonder how I would know anything about true wine cellars since I don't drink wine. Well, we happened to have a real wine cellar in the home we owned in Seattle. When we bought that home, the seller negotiated a deal whereby we let his wine collection stay until his new wine cellar was finished. His wine collection was clearly worth a considerable amount and he'd custom built a fancy wine cellar in the home we'd purchased that had sleek wood shelving, special temperature controls, etc. It was the real thing. And luckily for him, we didn't have any wine bottles to move in, nor any desire to drink his, so it was a perfect arrangement. Free storage for six months. Then, when he finally returned to claim his collection, that wine cellar became home for our extra storage. But, of course, we still called it "the wine cellar." So it seems we are Pavlovian conditioned/trained in every way! Especially when it comes to phraseology!
