As I showered, remarking how little pain I felt compared to the last time I was in the locker room doing such, I realized exactly why I'd screwed up my back! You will probably laugh.
See, there's this girl I know - I left a message on her voice mail, and to riff on her statement that she was bad with her phone, I sang the following into the mouthpiece:
I could be yours pretty baby
Yours and yours alone
But let me tell you honey
You're bad with your phone
Bad with your phone
It must have been a hit, because the next thing I knew I got a Facebook message saying that she wanted to hang out the next day. I think I raised my arms and shouted "YESSSSSS!" and pumped my fists and danced around my room and somewhere in there I probably moved in a way I shouldn't have. The pain didn't hit me until I woke up the next morning.
Anyway, as far as that particular girl goes, well, you can't win 'em all - and if you can, sometimes not right away**. ;-)
* - Since I was on a stationary bike, I think the metaphorical "further" is highly appropriate.
** - Not that I'm an advocate of living in false hope. There's a fine line between simply leaving things open and waiting desperately!
