I grow annoyed with constantly being asked, "Are you guys going to have more?" by people who know us.
Religious conviction, folks. That's what this is about. No, really. We actually believe on the basis of Scripture as witnessed to by the confession of the one, holy, catholic and apostolic Church that God intends for married people not to hinder the procreative process. Furthermore, we believe that Christians are supposed to live according to Christian beliefs, even if these beliefs are inconvenient and style-cramping.
So quit asking. I've already told you this. If anything changes, I'm sure you'll hear about it.
