When I was in school, we learned to read by learning all the vowels and the different sounds they made. Now, they just teach kids to learn by sight, which is probably a million times easier than trying to sound out every letter in a word.
I was also allowed to have cokes, ice cream, etc. at lunch. Now, kids gotta eat healthy. I sub a lot, and the kids are excited when they get to eat actual french fries instead of those awful sun chips.
