You know you have a teenager when you hear yourself complaining, “She has no purpose. He won‘t help. She only cares about her friends. He is so self-centered. Her room is a mess. I can‘t trust him. This is out of control. I can‘t stand her hair, clothes, makeup, or music. He wastes his money. She resents me and idolizes rock stars. He is on drugs and treats me like dirt. She is moody and irresponsible.”
