Hi there, i’ve just come downstairs 11:30 to have breakfast/ brunch and i saw the fridge door was not completely closed (but not wide open). It must’ve been left like that from around 8am when my mum left for work. I have had some cereal with the milk as it still felt cold but although it was cold it wasn’t ice cold like it usually was when i drank it. Will it be okay or should i bin it??
