Paybacks??????????

I had just gotten three dollars in quarters as change from a copy machine. I usually don’t give money to beggars as I figure they probably have more money than me, but in this instance, I felt the kid was telling the truth and stopped to give him the change. The window on the passenger side of my car hadn’t worked for months. I tried everything I knew to fix it but was unsuccessful. I thought I pressed the button for my rear right side window but pressed the one for the passenger window instead. When it rolled down and I handed the change to the kid I wondered if I was being repaid for doing a good deed. Where did the power come from to open my window?
