Cutting hair?

So, I'm trying to talk my sweet little angel into cutting her hair short for the summer.  It's super long but also super thin so it's a mess half the time.  And if it's not in a ponytail it's in her face.   I tried to say we'll cut it like her best friend and like the girl on tv and well... nothing!!  She refuses.  In fact, she said if I cut her hair she is moving out of my house.  Really??? Already??? I thought that didn't start till she was sixteen!!  What is going on with kids these days and where do they hear that?   So, of course I tell her she can't leave my house or I would cry and cry and cry for days and days and days.  Her reply, "Well, then I just won't be your best girl anymore."   Ok, I can handle that!   I think I'm in for some trouble with this smarty pants!

This is the look I got the first time I cut her hair short back in 2008.  She didn't want it cut then either.   Love her!!
