Yesterday I had one of those days. You know the sort I mean. Where shortly into it, you wish you had stayed in bed. You see, Boots had rung to say that my son’s glasses were ready for collection so I mistakenly thought that I would have to go with him. Why? Because I had paid for them and had the receipt. We made arrangements via mobile to meet at the same place as last week and at the same time. 12.30pm outside the paper shop in the bus station.
