I also think some see things as a long term image down the path on their journey. They can see where it will go. Some see a sprint and wish to remove things prematurely. Depends on ones final vision. I've been asked that myself on some trees why I have left something. Just needs more time in to develop further...patience may bring about a nicer tree.Because I like it.
If trees could talk... this one would speak about massive haircuts, artic frosts, and the Pandora's Hallelujah flying mountains.
