Binary choices

Life is a series of T junctions.
Every now and then you have to make a decision. Left or right. Up or down.
And you'll never know where the other road would have taken you. And there are no U turns. And you will never come back to a junction already visited. It's all forward, at full speed. Shitloads of T junctions.
There is an infinity of possible itineraries but you'll only ever know the one you picked. At each new T junction.
Whoever said that life was boring?
