A couple of days ago I poured myself the last of the box of Trix (the kind with yogurt), which I really like. Then I poured in the milk, and took a big bite. For some reason my Trix tasted kind of sour. I tried another bite, and figured maybe the milk was sour. I took a couple more bites to confirm my fears, and then was pretty mad because the milk was less than a week old. Then I saw that the expiration date had been the day before, and didn't think anything abnormal of it getting bad. I wondered for a moment whether it would hurt me to eat the sour milk, and then started eating some more, but after a few bites stopped because it didn't taste very good (and it's kind of gross to think about). I was pretty mad about wasting the last of my Trix though.
Of course, the next day I wanted some cereal for breakfast to go with my banana, so I went to the store a block away and got another 1/2 gallon. That was all well and good until last night when I went to have some more cereal (about 3 days after I had bought the milk). It was bad again, but at least this time I had been smart enough to examine it before I started eating it. My snack ended up being cereal without milk.
Today I got some more milk, and the idea popped into my head that maybe the fridge in the kitchen wasn't actually cooling. I looked, and sure enough, the top 1/4 of the fridge was a big block of ice. Needless to say, it's probably not staying cold enough in there. And I bet it's going to make quite the puddle of water on the floor if I let it thaw out.
