So go ahead, let someone you don't know use your home. What if that person is a recovering addict and just by chance on accident gets involved with drugs and is still staying at your house. Common sense would tell you not to do it. I wouldn't. BUT If I didn't have four kids and an extended sick family, I would be on my "free time" be trying in some other way to help out. I work at a restaurant and do what I can for the area I live in. Just yesterday, I gave out free food to the nicest lady ever, I could tell she just needed to sit in private somewhere and eat. Do what you can WHEN you can, it makes a difference!
