17. Your Partner Understands That You Come As A Pair
You literally cannot have one without the other and any future partner needs to understand that and accept it. You're both hoping that you'll marry a couple of brothers who will find it perfectly acceptable for the both of you to share the same wedding ceremony; because you cannot live in a world where she is married, and you can't just walk into her house and head straight to the freezer to help yourself to some of their ice cream. Having said that, you're bound to do that anyway. You're part of a pair, remember?
