Is it spring when the squirrels start romping?

Yesterday afternoon, I watched as two squirrles played chase outside my office window. They hopped from tree to tree and then back to the ground only to run in a circle and do it all over again. They paused once or twice to eat flowers off the tree that is blooming.

Everything is that bright shade of green that only comes with new blooming in the spring. The flowers are peaking up out of the ground. And this morning I have the space heater under my desk on as it is only 40 degrees outside and in my office building. But my toes are toasty warm.
