Spring is just around the...window sill?

For the last week or so, I've woken up to a group of birds that sit outside my windows and chirp.  I don't really know what they're chirping about...maybe the fact that it's actually been sunny most days lately, or maybe that Lebron put up 52, 11, and 10 last night at Madison Square Garden.  All these chirps make me think that it's spring...that somehow, overnight, winter left and it's now June, which is when "spring" usually hits in Michigan.  But alas, it's currently -2 outside (wind chill).  But at least it's sunny!
