Bugs in soup

So we had this speaker today and it was pretty interesting. He told a story about having lunch with an elderly lady, his father in law and brother in law. All of a sudden he saw something moving in his father in laws soup, he made sure the father in law saw it, all without using words. The father in law didn't seem to mind because he ate the soup anyway. Which is something I would not do. I think I would probably say I wasn't very hungry and grab a sandwich after I left. But this man ate it and he showed respect for the old lady. He could've yelled and flipped out like some people would do, and that would have upset her a lot because she was the host.
