Knock, knock, knock. The knock at the door caused the elderly man to wonder who in the world might be there. In his 60+ years of living in his home, no one had ever knocked on his door - NO ONE - in 60 years! Who could it be? There it was again. Knock, knock, knock. As he cautiously approached the door to open it, he saw two people standing there. As they introduced themselves, they said they were with the Extreme Community Makeover. They proceeded to explain that they were going to be working in the neighborhood in a couple of weeks and wondered if there were any projects that he could use some extra hands to complete. He certainly could use help. In fact, it was really nice to know that someone cared. And just think - he never would have known had he not responded to the knock at the door.
