I slept in my parent's bedroom until I was 15
Why would you do that? What happened after?
I started to stop that when I was 15.
It is not normal for kids to share bedrooms with their parents after being a young child. Unless you were poor there is no reason this should have happened.
That's the problem; why? I can see not having space, but my parents just wanted to enjoy my company before I went off to college.
It's wonderful you are all close like that, but didn't you think it'd be a cool idea to finally get your own room? You'd be able to give it personality and have your privacy! I hope you can get to do that in college.
