All I did was run to catch a shopping cart that was blown by the wind just enough to catch a downslope and head toward parked cars in the parking lot. It doesn’t seem like much, but I know that it can be annoying to come out of a store and see a new scratch or dent on a brand new car. It must have been enough, because one of the other patrons thanked me for my action, even though (I know this for a fact because she had parked next to me, nowhere near the carts) it wasn’t her car that was going to be hit. It felt good to do something helpful, just because it needed to be done. And perhaps someone will have come out of the store, to a car that would have been hit by a cart, but wasn’t, and did not have a good mood marred by an unexpected occurrence.
