If she is gay, more power to her.  However, there is such pressure to be different, and she is so young, that she may not be.  My daughter wrote me a letter at 16 telling me she was gay.  I supported her, told her I love her no matter what.  It turned out that she was not gay, just trying to wrap her head around feelings she was unsure of.  Today at 25 she is happily married to a man, and they have been together 4 years.  My point is this:  don't judge your children no matter what.  This is not a matter of choice, and when they're young, they need family support to figure it all out no matter if they are gay or straight.
