I bade farewell to my midlife crisis car today, my Audi A4 convertible. No more whizzing round with the top down, pleading with kids to get inside a bin liner before they can have a lift home from football. No more lying awake at night thinking someone's going to kick the front door in and demand the keys at knifepoint. It's been fun, but now it's time for a sensible runabout. More later, but this is a brief lament.
