I caught up with a friend recently, it turned out we knew someone in common and I mentioned in conversation they had two (now grown up) children. Said friend told me "but only one is hers". I have always known that one was adopted but it would never cross my mind to think of them differently.
Am I being oversensitive to think less of this friend? She is childless herself and doesn't know I've looked into adoption. I know it's a lot more emotionally complicated than many people appreciate but the comment made me see this long-standing friend in a completely new light.
