When, in the path of a glacier, you built your town 

You must have thought 

You'd had 10,000 years

But 10,000 years comes before you know it

And anyways, things happen 

To speed the course of events 

(You couldn't have forseen, for instance, 

Climate change, at the time)

I hope you understand

This isn't an admonishment 

I have built my life

In much the same way.
