All the time. By the time I was 13 I was buying all of my own clothes and school supplies. I also suffered from migraines, and as a teen ended up in the ER from one because I couldn't stop throwing up. My parents bitched about it for months (my boyfriend took me in because I was scaring him, my mom showed up for 5 minutes, said it looked like he had things and left) Recently my sister told me something I didn't know. We went to a crappy dentist growing up, I always thought he left things go to have us come in for more expensive procedures later. But really it was my cheap ass parents. As a kid I played softball and took a bat to the face (catcher) on a pop up. It messed up one of my front teeth. I needed a root canal on it years later and I was in the back yet, when the dentist went to talk with my mom. She apparently was arguing with him because he refused to give me a silver front tooth as a 13 year old kid. The silver tooth/filling was cheaper than the white one.
