When we do stop being our parents' little kid?

My 19th b-day is within 2 months, I'll be moving out soon and my parents (esp dad... he doesn't seem to understand I'm grown-up already) still think I'm their little kid.

My friends are coming and my father is going to likely embarrass me on my b-day doing his lame, old jokes, addressing me by my nickname from when I was a kid, sharing my pictures from my younger years, my favorite cartoon till age 11, etc. Until last year he still wanted to take me camping because that's what I used to enjoyed doing with him when I was little. I'm not their little kid anymore.

When will they stop seeing me as a little kid? I'm grown up already and got my own life. I'll be moving out soon.
