Eh, I don't know. Seems she wore her hair as an accessory and not care that much about it. She wasn't a long hair girl at heart.
The haircut cycle is fodder for views:
1) have long hair
2) start complaining it's so much work
3) "should I cut it?" (vote!)
4) cut hair
5) shock - wow so cute!
6) I miss my long hair
7) short hair is cut but takes work
8) grow hair out again
9) Go to step 1
