A crazy question

Some questions are better left not asked.
A few weeks ago Anni was reading "What to expect..." or something like it and mentioned -- warned? -- she may have mood swings during the pregnancy.
Since then, I've started playing a little game in which I try to detect when a mood swing swings by for a visit. They are not frequent and sometime subtle, which can make the game challenging.
About a week ago we were eating dinner when we got into a minor spat about something I considered trivial. I thought to myself, "I wonder if this is a pregnancy mood swing?"
I should have simply wondered. Instead, I took it a step further.
"Are you pregnant or just crazy?" I asked.
It didn't go over well.
I'm still wondering, but won't ask again for the answer.
