There is something to be said about working weekends. I hate to admit it but I love going in on the weekends when it is all quiet. I am my most productive then. I love how peaceful it is and how I can get stuff done without silly interruptions from everyone and anyone.
Actually, I did meet a colleague at work today - we had stuff to do and in a mere 3 hours, we managed to get WAY ahead of the game. :) Our hope is to not actually have to come in next weekend!
