Summer time

It's a beautiful, spring like day here in the North East. When I got up this morning I opened the windows and was pleasently surprised that I didn't freeze or get blown away and could hear the birds singing. (I was almost inspired to write poetry, but I can't and I was more interested in getting rid of the smell of the delicious if rather strong curry the wife cooked last night before a couple came to look at the house). Even now, I'm sitting in my office with the window wide open. Is winter now behind us or am I tempting fate? Will I wake tomorrow morning to find us snowed in? Is it wrong that we will get colder due to global warming and we are actually getting warmer? Or does everything just seem sunnier after a good nights sleep?
