M3, M2, and I were looking at the portraits that hang in my bedroom while changing M4's diaper. M3 looked at a wedding portrait and said, "That is you and Papa."
Me: "Yup, that was almost 10 years ago!"
M3: "That day you called Mary. You were wearing a pretty dress, so they called you Mary. And so they called Papa Joseph."
Me: "We got married."
M3: "Right, Mary and Joseph. And now you have a baby just like Mary!"
