One day, back when DH did most of the driving, I happened to be at the supermarket by myself. Came out, opened the boot put the shopping in and climbed into the passenger seat. A woman standing by the next car started up a conversation about husbands who disappeared on an errand of their own and failed to turn up when expected to drive home. I commiserated with her, miscalled DH and the penny only dropped when the woman said , 'At least you have the keys and can sit in the car while you wait'.
I waited a while, hoping her DH would appear because I didn't want her to realise how stupid I had been, but with no sign of him and a school pick-up looming I had to do something. So I got out of the passenger seat, slammed the door, said 'to hell with him' got in the driver's seat, and with the woman cheering and shouting 'Good on You' I drove off.
