First sign I was going actually going nuts, though, was on Saturday evening when I walked under the shower and momentarily went blind because I still had my glasses on.
But the big pointer to my deteriorating mental capacity was on Saturday night when Tracey and I woke up at about two o'clock because of a noise.
"What was that?" asked my 39 week pregnant wife as she sprang out of bed to investigate.
I, naturally, remained in bed. In fact, even my eyes remained shut.
As she slipped back into bed it occurred to me what the noise was.
"It was a gecko," I told her. That will put her mind as ease.
Maybe I wasn't speaking clearly enough. I was tired and it was the middle of the night.
"It was a gecko," I said loudly and succinctly in her general direction - my eyes still refusing to open. "That sound. It was a gecko."
"What the hell!! Go to sleep!!" she snapped.
This wasn't the 'oh, of course, thanks for clearing that up, darling' response I was expecting. Turns out the reason for her gruffness was she hadn't just jumped back into bed afterall - she'd in fact been back in bed for two hours and it was now four o'clock.
On the bright side, it's good practice for the impending nighttime feedings. I might mention that to her about 3am tonight :)
