A girl that was a year behind me in school went to fill up her car at the gas station and when it told her to select what grade she wanted, she kept pushing in 11 because she was a junior in high school. She called her grandma, upset, because she couldn't figure out why it wasn't working. *facepalm*
Then, this one girl in my friend Laura's math class...The teacher asked for someone to give her an even number to write on the board so this girl says "five..." and couldn't understand why everyone was laughing at her.
