Do you know that most foster children carry their children in just a garbage bag? I cannot even imagine being removed from my family, let alone having to carry my things in a garbage bag. What does such an action say about who you are? If you have an extra suitcase or duffle bag, why not find a foster care agency in your area or your state's department of child services and see if they will accept a donation. Most will be happy for your donation.
Sometimes making a difference in the world isn't changing the course of a river, but making it possible for someone else to navigate it.
