The "homes" of those in need. I work with a ministry every year that helps people in SC where I live. We March an army of teenagers into these houses and completely destroy the place, then build it back again in one weeks time. It's a great ministry, helping those in need but it pains me to no end to know that there are people right under our noses that live in horrid conditions. No running water, no working bathroom, floors fallen in to the point that the home is not habitable and yet they still live there, leaky roofs, no power, kitchens with only a camp stove to cook on, bugs and general nastiness everywhere.
Every year I participate, I meet another wonderful family that is in desperate need. It is a very humbling experience to meet these people, in spite of all of our blessings, and see how they merely survive on whatever scrounging they can muster. I wish I never had to see any of it, but it makes me grateful for what I have and it's very fulfilling to help the families that we're called to serve. You will never meet a more genuine and lovely bunch of people than those serviced by this program. They appreciate all they have, pitiful as it may be, whereas we generally do not. I've learned more from their gratitude through suffering than many other life lessons I've experienced.
