The sun can be shining but it can still be quite cold.
On snowy days, Bow tends to be less active. He is not upset by the weather, as in the case of a thunderstorm, but he just doesn't seem to want to do much.
In the spring and summer, Bow is active all day long. But when it is bleak out, Bow tends to nap more, even in the morning. This gives me a chance to catch up on my other work, such as editing and writing and even just posting things on Facebook.
Here is a video from yesterday, when Bow was napping:
All the ice from the previous storm had pretty much melted by yesterday afternoon, but this morning it was snowing again, and again school was canceled.
When I asked Bow what he thought about it snowing yet again, he accepted the situation philosophically. When it is cold out, sometimes Bow just likes to snuggle.
