Stumped

On most Fridays I lead a life coaching session with a colleague from the business. Whenever we can we go for a walk while we're talking; not only is it easier when you're not sitting face to face but the fresh (central London) air and exercise is good for both of us.

While we were talking today I noticed the recently pollarded trees, with all their stumpy bits. They always make me think of the Ents from the Lord of the Rings. I wonder if it hurts being cut back so brutally?
