We have more than once had to make an emergency trip to M&S because MrA has forgotten to pack his underwear/socks Petra
And he certainly didn't have the excuse that he hadn't put any on on the morning of departure!
Our worst incident of forgetting things was one year we were going on the narrowboat. In the study was a large quantity of things like pasta, rice, tinned tomatoes, fruitcake, beer, wine, washing up liquidetc that we would need for the fortnight and that I'd gradually accumulated over the previous few weeks. The joys of a self-catering 'holiday'.
We got on the boat, did various jobs and he asked for a glass of orange squash. I looked around and realised that none of my stores were anywhere in sight.
He had always insisted that he was the only one capable of packing the boot of the car when we went anywhere, so I had left him to it.
He had neatly packed everything....... except all the food and drink.
