bad milk??

tw for uncensored words

so i’m just posting this in hopes that someone else has gone through this and can tell me their own experience, however it went.
my dad left milk out in his car for several hours yesterday but for some reason put it in our fridge???? he left it out in the evening and i’d say it was in the low 60s to high 40s (fahrenheit) from the time he left it to when he brought it in. i used it in my coffee and my cereal this morning before he told me, and now im tweaking. i’m about to go to my swim teacher job and im so nervous. i’ve had bad milk before and it tasted almost carbonated, this one didn’t appear to have anything wrong with it
