As I tried to reverse my silver Honda Accord, I exchanged pleasantries with this frail, old man. He got closer to the car and started asking me something... I stopped, rolled down the windows to listen to him. He asked for a ride to his home nearby. I told him I was very bad with directions, and couldn't spare any time as I was on the way to pick up kids. He convinced me his house was very close to the library and he came walking to collect his mail and since it was raining he couldn't walk back...
I thought for a moment, sensed there was no harm, and opened the passenger side door for him... He directed me to his home - he was supposedly a retired professor from Rutgers, originally from India, both him and his wife taught at the university, wife is no more, no children, etc.
