We have a new high point!
I ask whether someone has been turning the fridge temperature up. (I know they have been, unless I do it in my sleep.) I am asked why I need to know, and I say that the reason I ask is because my milk has been curdling.
Evidence is presented to me that this is not because of the fridge!
This evidence is a thermometer saying that everything is freezing cold. I get to explain the difference between fridge and freezer, and that I don't keep my milk in the freezer, with the thermometer.
