I'm so tired...

Daughter 5 years old, asks to shave her shoulder-length hair and paint them in a terribly pink, that would be like the heroine of her favorite movie.
To shave I shaved, very tired of braids to weave her every morning, but refuse to paint.. trying to convince her that she still early:
- Look, your sister's 11, she's a teenager now, but still not dye his hair, because it's still early!.. mind you, still a child!
- Mom, she's a LITTLE teenager, and I'm a BIG baby!!!
