Today I forgot my lunch.
I also forgot (although less of an obvious oversight, given the weather) sunglasses, which would have been useful for some of the day, and an umbrella, which would have been useful for the other half.
I forgot that couscous is not ideal when eaten with a fork at the best of times, but especially when eaten with a fork over your keyboard while perched on an inappropriately-sized Ikea barstool at a worktop the incorrect height.
I forgot those Creme Eggs under the till were there for Easter Egg Hunt purposes, and not for general desultory staff consumption.
I also forgot that there is NO WAY to eat one quickly and furtively between dealing with customer enquiries, and the best a prospective bookbuyer can expect is for the staff member eating one (yes, that would be me) to panic, glance around frantically for somewhere to put half-eaten egg, fail as eggs traditionally don't stand on their ends, shove the whole thing into their mouth at once and end up communicating through a mixture of sign language and scribbled notes.
I forgot that accidentally chewing a piece of garish Creme Egg tinfoil can cause a nasty shock to your fillings.
I forgot that Converse Allstars are delightful footwear except when it rains, when they are frankly as useful as a blotting paper hat.
But I did get paid today, and tomorrow I will forget that whenever I spend more than 25p at a time my bank feels impelled to phone me and check my card hasn't been stolen by international racketeers.
