I think my sil and mil are talking about when to have my baby shower. They are discussing holidays being around then and I was planning my shower for Nov 19th until my sil offered to do it. It's just all of a sudden their conversation started to sound more secretive than it was before. I like not having to plan it but I hate not knowing anything. It kills me because I'm a serious planner.
