Walking your 4 highly various dogs after dark on a night with no moon on a street with no street lights can be an analogue for life.
You might think you know where you’re going, but you still need to rely on difficult, hard-to-spot signs to stay on the path. And the signs really are there if you pay attention.
You will see and hear and smell things you didn’t plan for, and unexpected stuff is often the most amazing..
If you stop without warning, whoever is behind you will probably knock you in the ass, purely by accident, and you’ll all fall down together after a stumble or two.
And every once in a while, some a-hole in a silver BMW X5 will blind you with their Xenon headlights and then throw a bottle at you.
