Parents ??????

I really do not understand my parents at all they confuse me to the point that I want to scream. They complain for some of the dumbest reasons ever but then after they complain they want to be your best friend. What kind of crazyness is that I often wonder if they are bipolar which Im starting to believe is true. Yes I know it sounds like Im being a brat or spoiled but I really not because I completely understand that they want me to be safe and what not but I dont fully understand the ways they go at certain things. In there minds they have my best interest at heart but in my mind there just fussing like usual every word that comes out of either my moms or dads mouth are to me complaints. But I just need to realize that I need to listen and not always fight them on everything that they want me to do. It also makes me realize that when I become a parent that I will not become a parent like them.
