I was on my own in the shop this afternoon because the other two went off to a banknote meeting. It was very quiet – just one customer in three hours. Fortunately we had two eBay sales so we did take enough to cover my wages.

We had tuna for tea. It was line-caught, though I’m not sure the tuna would appreciate the significance of this, or its part in my new healthy lifestyle. If the fish had thought more about what it was eating I may well have had a vegetarian meal tonight.

We had brown rice and vegetables with it. Last night we had fish fingers, mushy peas (from a tin) and potato wedges. I also had tartare sauce. Tartare sauce is a lot more palatable than virtue, but it doesn’t go well with rice.

Tomorrow I’m planning on fish pie, though I’m still not sure what I’m going to use for a topping. We’ve tried cauliflower mash a few times but it doesn’t settle well. Potatoes are always good, particularly with cheese, but they aren’t necessarily the healthiest option. I’m thinking of sweet potato, but the colour always seems too bright.

I really should try to become more adventurous with my food, though I’m not sure that changing the topping on a fish pie constitutes adventure. I fear that old age may have caught up with me (a) unexpectedly and (b) while I am too young to be old.

And yes, I am hoping that fish’s reputation as a brain food will restore my brain to near Jeevesian levels of intelligence.
