No one told us what to do. We all just did the right thing.
People will do that. When one is in need, or thousands need help. It's a natural impulse. You see it in children too young to even speak. I've seen it in hard men, that when no one is looking, care for total strangers. These acts fly "under the radar", or are seen as a "one-off" event. They are not isolated incidents, they are part of who we are.
The modern electronic world has obscured this truth in a fog of negativity. "If it bleeds, it leads" means that you'll only see the one soft news story at the end of the broadcast (that is my wife's favorite). No, the world isn't all fine. We have problems. But it isn't the cesspool of filth we are brainwashed to believe, either.
I trust my fellow man... generally. I do not trust how tribal groups are being formed like a creature on Doctor Frankenstein's lab. These conglomerate abominations force everyone to abandon their individuality in favor of the strength of the collective. People deserve better.
You are strong. You are good. You don't need to be part of some group to have an "identity".
Someday, it will be more than some old guy needing a hand. Or, a large metropolitan area. There may be people falling all around you. Do not shirk your responsibility. Embrace the opportunity. You do not need permission. Don't wait for someone else. YOU are that person.
Be strong, and be ready.
