Sometimes it just doesn't work, even when you do everything else right. Sad but true. Try to remember it's only milk. I once read that gardening teaches acceptance of whatever the weather etc throws at you. I learnt this the hard way when my husband's horse invaded my vegetable patch. Big feet, big mouth. Put a lock or something on the light switch. I once accidentally turned off my f-in-law's freezer while he was seriously ill in hospital. His daughter flew in from UK, went to the house, opened the freezer to get out something to eat, and found....something like your cheese, but much more if it. I was not popular. The problem was the freezer shared a double adapter with the washing machine, and as f-in-l always turns that off at the power point, I did that too. Only he does it by pulling the plug....
My commiserations.
