I see an airplane in the distance, and I watch it come in a burst; going back is also rare, there aren't many bullets left, how do we count this?

A woman suspects that the fish her husband brings back from night fishing are bought, and she cannot be sure. Then she has a clever idea and posts online, asking the internet experts to identify it. Sure enough, there are experts online, and one female expert replies most brilliantly, saying: Next time he comes back from night fishing, you can ask him for a sample; if it's thin, then it’s bought; if it's thick, then it’s caught. … What a genius! To come up with such a good idea.
