I received a random act of kindness

As I was standing at the back of my car this afternoon, raining drizzling down and starting to fall more heavily, unloading the groceries I had just purchased, a sudden gust of wind caught my shopping cart and propelled it away across the parking lot.  I caught it before it had rolled too far and was back at my car when a lovely young lady came up and started helping me unload my groceries into my car.  She said "I saw your cart get away from you, and since I have an umbrella, I thought I'd come and help."  How nice was that?  I feel like I was really blessed by this kind gesture today and am excited about the prospect of paying it forward.
