Give your seat up on the bus or subway

I don't really know how to create my own act of kindness and this is the one that looks more like it so I will comment it here!
Yesterday it was raining cats and dogs and I was going home in my car. Suddenly I saw a woman walking at the side of the street. I opened the door and told her I would have carried her home. She lives at 1 km from there. She said she was very wet but I answered I did not care. She was shy and very surprised but when I left her in front of her door, she thanked me many times saying that was unexpected. It was 3 min of my time but made my day
