Park exploration

A familiar park feels fully known because you walk one path through it. Turn off once and it turns out to be bigger than you thought.

Go to the park you visit most and at the very first fork turn where you normally do not. Keep walking until the path brings you to a spot you have never seen: another pond, a back corner, an old fence, a clearing. On the way note three things you would never have spotted on your usual route — a tree, a bench with an inscription, someone's bird feeder. Walk to the edge of this new part and stand there a minute without reaching for your phone. Go home by a third path, not the one you came on.

What else in my life do I consider fully known, only because I walk it one way?
