I twirl my hair with my finger, i have done for years and i can't stop it and i have tried, even to the point of sitting on my hands, because i worried that everyone would think i fancied them, you know how they say thats how women flirt ( oh yeah, but not the habitual twirlers)
and it drives my mum mad, even at this age she says "stop doing that with your hair"
I had my hair cut to shoulder length once, i thought that would stop me, but it made me feel so sad that there was nothing there to twirl
had to grow it long again
