This girl always had her head in the clouds... her mother always warned her that if she wasn't careful, it'd stay there. Ofcourse as any teenager, she didn't listen to her mother - and as a result, on a day in class when she was staring outside and dreaming again, her head really floated away from her body!
Since then, her mother makes sure she takes special care to stop her head from floating away too far; before, she tied her pigtails to her coat, but now that she cut her hair short, she decided to wear cute hats with tassels instead.
Looks like her mind is drifting off watching the snow again - good thing her mother made her wear the hat!
