How many people hate it when your milk goes bad?

i hate it when the milk spoils. its weird because one of my milk lasts up to like 2 months. because i'm allergic to milk. so this has a weird taste and it doesn't smell like milk when it goes bad. so i don't know what to think am i'm drinking old milk? is it bad for me if its been open that long. only because i can't smell it going bad does that mean it has the same exffect of real milk going bad in me. this is what always comes to. but yes i hate when milk expires i wish it would last longer but if it did i guess milk wouldn't make that much money anymore

I don't mind when it happens, because I love curd. That is to say if the milk is not pasteurized, because then it just goes bad and doesn't form curd. Really nice with some sugar.

What's even worse, when you find out it's gone bad after drinking it lol. I usually watch the expiry date, and then smell it before drinking. It's usually good for a few days after the expiry date though. That's just the last day the store is allowed to sell it by, at least here in the US anyway.
