There's no such thing as "too long" when it's someone elses hair you're referring to.<br />
If she's comfortable with 55ft of hair, then it's just right for her... whereas you may only be comfortable with 1ft of hair, and so that's just right for you.
I think if your hair is affecting the quality of your life, it's too damn long.
Really?? My hair never even grows longer than my back, maybe it's some sort of genetic disposition?? When I had dreadies, they took crazy long to dry though :D
