I'm in my mum's car

I had a 9am appointment at the ophthalmologist. I booked it 6 months ago so quite why I had to wait almost an hour to see the doc is beyond me.
However, she did a thorough job, even dilating my pupils to check the moles on the inner surface of my eyeballs, this meant I couldn't drive home and had to be rescued by the (no longer a) teen, who relished the chance of driving my car...
