DW is a friend!    When I was starting with a laser he was very helpful sharing projects, methods etc.  LJ days.
When my daughter was fighting breast cancer he shared  his pocket angel laser plan.   I used it on many heart shaped pink breast awareness boxes I made for  my daughter to  give to fellow bc patients.   Helped her a lot.   She is now cancer free.   
DW was always caring and shared his knowledge as well as trials and failures.   I respect him a lot.
