Or....miracle of miracles....she actually respects her parents and does what they say.
I remember when i was 18 i had all sorts of stupid ideas and did dumb shit, and my dad would put me in my place because he gave a shit about me. Apparently everyone on Getbig was mature, wise, financially independant, and told their parents to fuck off....at 18 years old...LOL
My parents were not control freaks who told me who I could or could not spend time with. By the time I was 18 years old, they figured I was mature enough to be able to pick my own friends and they were right. Did I have some lame brained ideas? Probably, but I knew I was responsible for how my decisions might affect my life and that "mommy and daddy" weren't going to bail me out if I screwed up.
At 18, I was fairly mature and financially independent (not living off my parents, but not wealthy either). I respected my parents, so I didn't tell them to fuck off at 18 or 38 years of age. I did rent an apartment at the beach and moved in on my 18th birthday. I never lived under my parent's roof after that because I didn't need or want to.
Apparently, your dad was still treating you like a child when you were 18 years old. Not to worry, coddling one's adult children seems to be rampant these days. This is partly why some young adults act so irresponsibly, imo.
