In Tesco this morning, a passing woman gave me a sly sideways glance and said ‘I saw that’. I don’t know what I did. As far as I remember, I was deciding between brands of chicken pie. Maybe I committed some major faux pas of which I’m not even aware. Like ‘thou must not dally in front of freezers on a Monday’ or something. Or maybe it’s a secret one, created purely to confuse young men. That’ll be it.
