This happens every year or so for me. I get the sudden urge to get rid of basically all my hair. At this point it's between chin and shoulder length in a surprisingly versatile bob. I can do all kinds of things and I rarely have a bad hair day. My only reason to cut it would be my preference for shorter hair.
I like long hair. It is pretty and you can do braid crowns and top knots, curl it, straighten it, do one of those faux bobs.
But it never works out for me. For other girls, having long hair is like having two arms, but for me it's like having three. Once I finally get to a "good" length, I feel limited and less confident.
In the past, when I've gotten the urge, my hair has disappeared within a week. Right now, I can't decide...
