When I told Boyfriend about my mom's desire to have us married by a minister, his response was:
"What, because if it isn't done a minister, we aren't married in the eyes of God?"
(Note: read that sentence above in the most sarcastic voice you can muster. Then make it 37.2% more sarcastic, and that's how the sentence was said.)
I told him to make sure to he said exactly that, in exactly that same tone of voice, when we are visiting my family for the Christmas holidays.
After all, if the wedding choices we make are going to break my mom's heart, I'd prefer her to think that they're not my choices...
