I would kill for a custard cream to dunk in my tea right now. If I could trust myself to eat just the one and then carefully wrap up the packet and put it in the cupboard until the next cup of tea, I would either be drinking six cups of tea an hour, or have had my body invaded by an alien force that didn’t like biscuits. Sadly I am alien and willpower free, so if I want to undo the damage done over Christmas (i.e. since middle of November) then I have to steer completely free of that aisle of Sainsbury’s. Easily do a packet in one go. Easily.
