when i found a small box in grandpa's bag, he zipped it open and showed me something he called 'cigarettes.' he said they were not for kids, but he also told me about a principle where people refuse to acknowledge things that can harm them, like choosing not to smoke. grandpa explained he quit smoking long ago, before i was born, because he wanted to be around to kick off again every morning with a big smile for me. it was a prevenient decision, he said, because it meant he chose to take care of his health before anything bad could happen, all so we could have more sunny days together.
