I prefer to have short nails, because otherwise, my hand hurts whenever I want to make strong fist and writing becomes inconvenient.
It if comes to girls: I like them to have short nails as well. I don't see why some girls consider long nails to be beautiful, because it just isn't. Extremely long nails look repulsive.

I like to see short nails on guys :) for girls, I like to see long nails if it has colored nail polish on it.. :)
But for myself, I prefer short nails as I don't do colored nail polish and I feel more clean and comfortable having short nails :)
