Despite my griping, I am proud of her. She has always been happy and respectful, never went through a rebellious stage, never dabbled with drugs or alcohol, and doesn't sleep around. She pays for her own car license and insurance, pays her own health insurance, and I even convinced her to start an IRA last year. While she technically lives at home, we rarely see her as she's busy with her two part time jobs, volunteering, and recreational activities.
Chronologically she may be 28, but she still looks like she is 16. Everywhere we go people ask her "so are you graduating high school this year".
She also acts much younger and has such a naive view of the world. She's one smart cookie, but very immature for her age. I suppose that's why it hasn't felt so weird that she lives at home, she still seems so young.
