I believe one thing is that you have to hear some very heart wrenching things. You know whose getting abused or neglected, who know whose family is on hard times, you know who is in foster care, you know how kids feel in the darkest way and all things surrounding that. The other thing that stands out is having to say goodbye once you leave or the kids leave. You can have them for so many years and build those relationships. Seeing them go and move on is difficult.
