how difficult can that be?

so as i walked towards my car this evening, someone asked me to throw a tennis ball back onto the court. figured the losers could use some help. gallantly picked up the ball, handed my bag to a friend, took a few steps back, swung my arm... and sent the ball flying diagonally behind me. hmph. tried again. this time, i sent it diagonally in front of me. and drew wild cheers for the entertainment. awful awful performance.
