Growing Up

Recently my child development prof asked us a question that was very thought provoking, it was when/if we experienced a transition from childhood to adulthood. I've been having issues dealing with this the past little while. I know there is no way I'm all grown up, I'm just not there yet. I do have a lot of adult tendencies, but I also have a very childish side.
This weekend I went to Landon's house for the weekend. His family was moving and being my awesome self I was helping them move. Unfortunately I made one big mistake and forgot my cell phone in Peterborough, this mistake made the lying to my parents about my location very difficult. My mom is paranoid and freaks if she hasn't talked to me in 2 days. Sunday morning I checked my messages and there was a message from her saying that if I was in Oakville I should call her and she was getting worried. But it was a lot more condesending and I'm your mother-like. So I called her and left a message saying where I was etc. Now, a lot of people probably wonder why I just don't tell my mom in the first place, however, that doesn't allow me to stay over at Landon's. Landon and I being a couple like that time together, so I just don't tell them, it's easier that way. Plus, I'm an adult now, I should be able to make these decisions. My parent's don't treat me that way, despite the fact that I'm pretty responsible and don't live with them anymore! It's hard to be in University because there's such a shift when you're at school and when you're at home. At school you can stay out as late as you want, or just go out as late as you want. At home there's just a certain code of respect you should follow. So I'm stuck here trying to still respect my parents and not be too pissy when they're invading my privacy but what am I really to do? In some ways I'm still finacially bound to them so I don't feel I can be rude, or insult the way they talk to me or try to still raise me. They still have that hold on me and it drives me crazy!!
My dad wrote me the sweetest message on my birthday card - it said - "I could give you a sermon about growing up - but you don't need it (Except for your messes" It actually brought tears to my eyes because it said SO much more than just that. I know that he sees me that way, it's just my mother who has issues dealing with the fact that I'm not 8 anymore. She's always reminding me of things that I already know. She reminded me to organise the rest of my placement for con-ed. Thanks mom, really, but I am capable of remembering certain things!! This weekend she had a hissy fit because I missed classes on monday. Ya, not such a good thing, but whatever, I'll make up for it.
My parents don't seem to understand this whole concept that I have to make my own mistakes in order to learn. Last semseter I messed up, I was a bum, I was sad, dwelling on my problems, didn't work hard enough - and I got my grades - so hello, I'm working a lot harder this semester. (Haha, I'm on the 2nd week). But I know that I have to pull up my socks or this year.. well, ya. I don't need someone to tell me that!! I know that I messed up and I'm trying to fix it, so let me fix it!! I still have this urge to rebel whenever my mother tries to push something on me - I've always been that kid in my family. No matter what if someone invaded my space, or tried to push something on me I would back away so fast. I guess I've always had that certain degree of independence.
I told my parents this weekend they had to back off and let me make my own mistakes or I would never learn. They actually said it was "bull shit". Um, not to me thanks! I've already learned a lot this year from being on my own and screwing myself over. I know not to waste money on things not really needed, I know to go to class and do the work. I'm learning so gosh darnit just let me!!
