I'll Jump

Two roads out of the city
Both of them I’ve been down
One of them takes you to water
The other leads back into town
Now if I said
That one of them’s teenage
And the other is fully grown
Go down, go down
No boundary’s in the distance
It all goes on and on
A meeting place or a junction
You’re bound to get it wrong
But a petrol pump and a fruit stand
A fruit stand and a pump
Slow down, slow down
If you touch me on the shoulder
I’ll jump
