In the middle of last night, D. woke me up by saying "What's so funny?" I mumbled something and went back to sleep, too sleepy even to wonder what kind of a strange question that was given the situation and timing.
This morning over breakfast, he asked me what in the blazes I was cracking up over at 3am. Turns out I was laughing (heartily) in my sleep.
I don't know about you, but this makes me laugh even more.
