My rationale for ownership met with a stony silence.
"It'll also be useful when I'm in the gym, or out jogging," I added.
"It not only tracks my exercise movements, but measures my heart rate. And because it's voice-activated, I can also call my friends and proclaim how well I'm doing on Facebook or Twitter, because I'll have these social media services at my fingertips," I explained, tapping my wrist.
"The only problem is," replied the caregiver wearily, "you never diet or visit gyms or go jogging and even if you did, you don't have any friends to proclaim your progress on social networks."
"Perhaps," I retorted, "if I owned such a watch, it might assist me to become more healthy, especially if it gives me little warning beeps every time I consume too many cheeseburgers and fries. It's bound to be monitoring my blood pressure and glucose levels while I eat."
After another long silence, the caregiver finally asked, "tell me, does it have a tracking device?"
"Naturally, it'll include a GPS location app," I replied loftily.
"Does that mean I could always locate you, if you absent-mindedly wander off?"
"Probably," I replied cautiously, not understanding the drift of the conversation.
"Well, in that case, I've changed my mind," the caregiver proclaimed.
"I think now you're a fully-fledged octogenarian, you should definitely wear one - especially when leaving the sanctuary of the home," she concluded, sympathetically patting me on the head.
Sometimes, I don't know what makes women tick.
