Paying it forward

I was parked outside a large facility in Columbus, Ohio doing paperwork when this school bus driver approached and asked me if I did shingle work. I asked her what was going on. She said she paid this guy to roof her house, did half and never came back to finish it. I asked, did you pay him for the whole roof? She said yes. I told her I would do it for $500. I tore off the back of the house and shingled it in 1 day by myself. She was short on materials but it was 99% complete at this point. She tried to hand me some money and I told her to keep it. I said you already paid for it. God brought you to me and I'm not taking any of your money. She instantly started to weep. God has rewarded me 10 fold since that day. Just a guy trying to right a wrong in the world. God bless you all. The thumbnail is my truck loaded to the max with her old roof.
