Mother on a Broomstick Talks

This morning I have a couple of questions to ask Mother Nature.  As I understand it, we have already begun meteorological spring.  I know this because we've had some typical spring weather in which we have sun, wind, rain, hail and possibly thunder and lightning all happen the same day.
So here's my first question:  ARE YOU SERIOUS?  Check out our little snowfall last night.

Here's a pic of last week when spring seemed so close.

Which leads me to my second question.  Why is it that the 63 degrees on the sunny day above seemed almost balmy and the 60 degrees in my kitchen this morning felt like the frozen north?  Apparently the furnace is on the fritz and I have no heat downstairs.

And while we're at it, why do the dogs need to go out to the deck and check on the snow every ten minutes?  Why don't they believe me when I tell them that it's just the same as it was the last 5 times they went out?  And finally, why am I not thinner from running up and down the stairs all day letting them in and out?  Please tell me, Mother Nature, because I need to know.
