Here's a news flash for all of the children out there, including my own at home:

If you are mad at me, that's fine. You are mad at me because I parented you. I am not your best friend. It is my job to make sure that you get what's best for you, and to make sure that you hopefully, someday "turn into a person that I would want to hang out with". Until you're a self-sufficient adult, and no longer require "parenting", I am not your best friend. I am your parent. I don't want you to get sick because of candy breakfasts, avoiding homework, or late-night Barbie sessions the night before school.
