This happened about ten years ago. I was living in Guadalajara, Mexico, teaching English on a low salary. I walked past an overgrown lot going to and from the school every day. A stray dog lived there who I called Chucho. Most mornings I brought her my table scraps wrapped in a tortilla. One morning I called her and she came running and waited in anticipation as I opened the bag and discovered — a tasty snack I had been saving for myself! I had grabbed the wrong bag! When I looked at her hungry face, what could I do but give her my yummy treat? (I had to think about it though!) But it was a small sacrifice to bring a little bit of happiness to a sad and hungry dog.
