1. I drove my car to attend a routine yearly health scan, at midday; that I've missed for the last six years.
2. Later, I'll drive myself to the vet's surgery to collect my dog at 6pm.
I'd be over the drink/drive limit by midday and multiple times over by 6pm, therefore I couldn't drive. So today I can do a simple thing, like sitting in my car and driving myself at any time of day. I am no longer a self-imposed prisoner in my home, due to listening to the AV.
