Just quit whatever it is they are kicking you out for and tell them you're done with it and you'd like to come back. Your parents are educated, and more than likely know what's best for you in the long run. They've been around the block more than once I'm sure. The only reason I've ever seen people kicked out of home (and I've seen it happen plenty of times), is because they were completely fucking something up and not only harming themselves, but the people around them also. This includes both emotional and physical harm. More than often it's drugs and the family suffers because of this. Judging by your first post you don't have much respect for them (maybe reasonably so) and seem rather immature, but if you don't even say what they are kicking you out for, I'm forced to believe it's your fault.
