If you ever meet Zeno’s turtle on the road, know that he is prone to half measures. For if the two of you are on the way to town, he will only go half as far as he needs to and stop regardless of how much daylight is left. He is rather rule-bound about it. Don’t try to prod him or convince him of the futility of always only going halfway. Worse still, don’t try to pick him up. No matter how much you have enjoyed his company, and he is pleasant for a turtle, if you try to carry him the remaining distance, he will bite. And if you whine to him that he’ll never actually get to town, he stoically replies, maybe so but I can always be as near as you need me to be.
