Don't be too rigid about things today, especially social arrangements. You might have a specific idea about what you want to do for fun, but not everyone is going to agree with you: and they won't be flexible about it. So you're going to have to be. It's a familiar pattern with you two, and one that might be starting to get on your nerves. Do it again this one last time. Then, make a mental note that if this happens again, you two need to have a long talk.
