You know you’re growing up a bit when you can spend 2 weeks traveling with your sister and not argue. It’s a serious accomplishment. I recently went on a holiday with Katie and we didn’t fight at all. The closest we got to an argument included some slightly heated bickering over whether or not a dessert we were eating included condensed milk in the ingredients. I think the conversation ended with the phrase, “You asked for my opinion and you got it. Now stop telling me I’m wrong!” It was then that I realized we really needed to change the subject.
