how come when you do one thing you end up doing more?

i was pretty tired yesterday so thought i would just pop some washing on, then empty dishwasher to put on a new load.
well first off i took the cutlery out, opening the cutlery drawer it looked less than pristine so all that came out. took tray out wiped out drawer then tray, sorted all cutlery. some was washed pre dishwasher days so put that aside to wash too.
then after putting them away I needed to wipe the tops down, suddenly thought i had no overnight oats in the fridge, i usually make three or four to keep me going a few days. anyway then i thought better top up my home made yoghurt so made two more containers of that. yes fridge needed a wipe then the floor, emptied the kitchen bin, then hoovered the carpet. Honestly so much for a quiet afternoon
