I had an incredibly positive example of how good people can be happen to me last week on my way to an appointment. The bus took me about 15 blocks from where I wanted to go. I thought I'd checked the route several times but still ended up far away from my destination. I only had credit cards and a few pesos and knew that cabs can be fickle about accepting cards. Still, I tried hailing cabs and the first 3 told me 'no'. The 4th one, driven by a kindly-looking grandfather type in his late 70's, pulled up and when he said 'no cards' he insisted i get in. I showed him the address and we took off. As we neared the building, I was asking him what about the fee? I offered to take his address and other options but he asked for my address instead. "At 4PM, I will come to your house and you can pay me tomorrow. Don't worry about it." I was so flustered and surprised that I was just sputtering, "muchas gracias muchas gracias senor muchas gracias...." He waved me on my way and it set my mood for the whole day. He did show up the next day and I had the money ready for him in an envelope. He thanked me over and over and I thanked him repeatedly. I just wanted to share that with the many inconveniences I/we all experience in learning the landscape of the city, there are many times I say, "This is why I want to live here."
