Help! Quick!

sorry to bother you guys but this is sort of two questions but anyway.

I want some cool side bangs but for thick medium length hair i was also thinking a little bit of layering at the back to mix it up. I need a picture of some to show a hair dresser so could you post some pictures of cool side bangs sort of like this girl has

my other question is how do I convince my parents to let me go to the hair dresser tomorrow in the shopping mall. my parents are going away so I'm staying with a friend and we are going but my parents won't let me go unless they are there. (It's not as if I'm going to get some other really strange hair cut!)
