Rob, I hope you get good news on the knee - and that it just calls for PT. I can totally understand the benefits of exercise - as I think my lack of it has helped propel me into a state of mild-to-sever depression over the last few weeks (the PT I do for the torn ACL just doesn't get the blood flowing...).
It's good to hear you sounding so upbeat and to see that you're identifying and pulling yourself out of some dark places.
What a shame about your GF's car - such random frustrations can be so taxing at times.
How are things at school?
Any plans for Halloween? I'm hoping to take my S3 to a pumpkin patch this Saturday (there's a train involved, he loves trains) - so that should be fun.
