I am constantly forgetting to charge my toothbrush. Everytime I brush my teeth without it being electric and think 'really must remember to put it on charge once I'm done here' yet day after day I leave the bathroom straight after and forget to do it
Milk is the other thing I'm always forgetting to buy even if I remind myself of it in my head about three times throughout the day. Still every morning I open the fridge and only then I realise I'm gonna have to drink my coffee black again today
I also never remember which side of the car my petrol cap is on which is why Niamhs revelation about the arrow on the dashboard icon was genuinely life changing
