There are three signs that mark the path of a boy maturing into a man:
1. Walking around puddles instead of through them.
2. Getting a haircut without being told
3. Coming to appreciate the brake pedal more than the accelerator.
More playing around at work with macro photography....the brake pedal on my truck, with the right side clearly heavily worn away from countless thousands of times switching between pedals. On my last truck, I actually made holes in and wore the tread off of two of them, having to replace them.
