Spare a thought for your poor shadow the next time you do anything strenuous on a sunny day, because our shadows are compelled to mimic us whatever we do without even a noticeable time lag
and although it's possible that perhaps I've got this the wrong way round (and that it is actually us
who are condemned to follow the movements of our shadows) it is better to show some sympathy than none wherever there is any doubt.
So a big hand for our shadows, those unsung umbrae!
Here you may view my shadow standing on top of a peak while another shadow climbs up to meet me. This doesn't mean that my shadow is a better climber than the other shadow. Quite the opposite, as it happens...
