Oh dear, why do they still treat me like a child

This is my first taste of extreme disagreement with one of my parents. I have been abnormally lucky these past 19 years to have parents I've considered as two of my best friends and confidants. I've enjoyed talking to them and going on a bunch of trips, etc, but I find that relationship getting proded a bit when I talked to my mom today about a piercing. A stupid insignificant piercing. People I have talked to said "Don't worry about it, just go and do it and don't even bother telling your parents. Youre over 18." But that isnt something I can do. The tattoo and piercings I got before went over fine and I talked to my parents before each one. I guess I've prided myself on being able to have an open dialogue about them and eventually coming to an agreement. It didn't work out as well this time though. I put together a packet with tons of information, safety precedures, and the like, got up the guts and talked to my mom about it. She freaked out beyond my expectations. Said that I could do it, but that she hated it so much and didn't want to see me ever if I did, and was almost on the brink of crying, then got so angry that she lashed out all day at my brother and dad. She seemed to take it as a personal attack against her. This sucks. So obviously I said I wasnt planning on getting it done after that, but this is my first experience with being torn between really wanting to do something and wanting not to piss off my mom. I think Im starting to realize the hard time that some of my friends have with their parents. I just hope this one works itself out. I guess I won't make a big deal out of it, don't want to fall into that ridiculous trap of teens who blow everything out of proportion.


For now, I've baracaded myself here in my room with the computer (as only a true computer nerd can) and then will be out with friends so hopefully by the time I get back this will blow over.
