Why can't it be sunny on the weekend?

Seriously!
Why couldn't it have been sunny and warm yesterday?

I came home "early" today (early just means I didn't stay late) so I could grab my book and hang out in the back yard before it got cold, dark and cloudy. The clouds are actually rolling in at this exact moment.
So, I neglected Jupiter and was outside with my lemonade, surfing the net and reading my book in record time today. It almost felt like summer!
