I was walking home from work about 1/2 an hour ago, and I heard someone making weird noises across the street. Turns out it was a mentally disabled guy in a wheelchair who'd gone off the side of the road, and was stuck against a fence. I rang the doorbell of a nearby house, and got the guy who answered to help me help the guy in the wheelchair. Apparently, he'd been stuck there for 3 hours, and could have easily been stuck their all night, since I couldn't even see him as I walked by across the street. It feels really cool to be able to have helped him like that.
