Is 13 too old for an Abbyism? :)

We were discussing the topic of taxes in the car today.  Marshall was asking me all kinds of questions about them and why we pay them.  He was thinking it a bit unfair and I told him about that old saying..."There are two things you have to do in life".  Well, some of what I say must be sinking in because Abby piped up with "Yeah, clean and pay taxes!"
