"I dunno," he murmured, shrugging his shoulders and rolling his eyes heavenwards, adding, "she's been acting weird all day, cleaning and scrubbing everything."
A sure warning sign that something dark is preoccupying the caregiver's thoughts is when she starts sanitising the property with a formidable collection of powerful disinfectants, earning herself the nickname Chemical Ali.
A visit to the toilet confirmed my worst fears: Chemical Ali had been at work with steam cleaners and ammonia-type products that took my breath away.
Protesting is pointless; the caregiver is convinced that only the most powerful chemicals known to man can combat the careless bathroom habits of an elderly man and two young boys.
Following an excellent dinner, I tried to recover a few brownie points by cleaning up the kitchen and taking care of the dishes, but to no avail.
Somehow, the stiff formality of the evening appeared to have set like concrete.
Long experience has taught me that when a woman presents unfathomable social behaviour, the best thing to do is to gracefully retreat by going to bed, and trust that all will be well again the next day.
I was just drifting off to sleep when the caregiver shook me awake again, handing me an envelope. "What's this?" I asked nervously, wondering if it might be divorce papers.
"Open it now!" she commanded. It was a red heart-shaped card, with the message, "Happy 15th wedding anniversary! Darling."
One thing you have to say about women - they know how to stick the knife in, right up to the hilt, when you've forgotten something important.
