We get our milk delivered - it gets left in a little insulated box on our doorstep. Yesterday we forgot to bring it in till midnight ( it had been there since 6am). Dh claimed it was cold. I want to chuck it, especially as we have 80 yr old relatives for tea today. Dh thinks I'm being ridiculous and says how do I think people managed before fridges were invented. Please advise, wise mumsnetters!
