The tipping point

I think I may have figured out the signal that we've moved from fall into winter (other than the leaves being off the trees, having to scrape frost off of the windshield in the morning, and seeing Christmas decorations start to go up around town). In fall, when the weather first starts to get crisp, you bundle up to go out but inevitably it's warmer than you first think and you curse yourself for bringing a jacket that's just a bit too heavy, and why on earth did you grab a stocking cap on the way out the door? Once it turns to winter, you bundle up to go out and it turns out to be colder than you thought. Why didn't you wear a heavier jacket, and why did you grab your lightest pair of gloves? I'm afraid we've reached that tipping point here...we drove to Bern yesterday and as we walked around we kept waiting to warm up, but even when we found an isolated patch of sun we got colder and colder the longer we stayed out. On the plus side, that means ski season should be just around the corner.
