S10 came home from lunch with H today and told me, "Dad kept flirting with the waitress at lunch."
Me, laughing, "Flirting? What do you mean?" S10: "Like the waitress had a tattoo, so dad was commenting on her tattoo and saying that it was cute and showing her his tattoo." S10: "And he told us that we need to learn how to flirt too! We said no thanks we do not want to flirt with people who are double our age."
