@GracieGirl,
I've had various crushes in my life, some of them unwise one way or another, don't get me going.
Sympathetic as I can be to the phenomenon of having a crush, I cannot even imagine having a crush for Justin Bieber.
Why do you pick him to have a crush on, girl?
I'm guessing his safeness. Do you find him sexy? Or his goodness?
Sexy, good word.
