Now, I may be struggling on practical DIY, but one thing I'm expert in is shopping.
I've now been back and forth to the megastore, buying this and that, discovering a new enthusiasm for purchasing manly-looking tools and allied stuff, so much so that I was even tempted to buy a large metal storage unit to hold my growing list of DIY essentials. I even had to transfer my old truck from the holiday house to carry some of the more heavy-duty gear I've been indulging in.
So, dressed in my tattered shorts, paint-splattered T-shirt and armed with my truck, I felt assured that I reflected a certain savoir-faire, suggesting that on the surface at least, I looked like a proper Kiwi DIY sort of bloke, ready to tackle all manner of home improvement jobs.
After re-plastering my earlier botched efforts, I began drilling again, having carefully checked the surfaces with my newly purchased stud finders, spirit levels and measuring templates.
To my horror, the heaters once again ended up suspended on a slight angle, leaving me mystified and blubbing in despair that I'm still a long way from truly earning my home-handyman's stripes.
Later in the day, the caregiver, more practical and competent than me, noted that the heaters' fixing brackets were not aligned correctly, suggesting a manufacturing fault that clearly made it difficult to hang the units correctly.
With the appliances hastily replaced, I've recommenced machine-gunning the walls again, ever hopeful that somewhere in my fragile physiological makeup, there is a double helix encoded with that magic DIY molecule.
