Expired milk update

I was curious to try the milk yesterday at seven days past the expiration date, which would have, I believe, set a record for us. But I forgot to say anything to the kids about it, and when I looked in the fridge that half gallon was gone. Drunk up, without a word. More evidence that its drinkability was not just some twisted frugal bias on my part, for they surely would have yelped if the milk tasted funny.
