trying to teach your mother how to format an Excel spreadsheet. Especially when she would rather you just wrote down a detailed list of instructions. She'd rather just blindly follow a recipe than actually learn the how & why behind each step for future use. That way when the shit inevitably hits the fan, and she can't get it bolded & aligned exactly the same way, she can blame your crappy incomplete instructions and absolve herself.
My latest pet peeve: People who click the mouse once, and when it doesn't produce their desired result, click-click-click twenty times rapid fire style and act surprised when the result is something undesirable.
I love my mom :)
