A second love for many years coming to an end.

Wow, you did a great job on that! I went through a similar rite of passage about a year ago. When my boys were small I built from scratch, a large outdoor wood play set. it had swings, a clubhouse and a slide. it filled me with great pleasure to see them and their friends enjoy it for many years. As they grew older it got used less and less and I finally made the decision to tear it down. I'm not going to lie, I shed a tear that day. I can only hope with my kids, and yours that the good times they had are stored away in their file and as they grow older they will pull them up now and then and smile inside. It sounds to me like your a great parent.
