why do some of the girls cry at the ones going home, it’s a contest, should be happy they aren’t going
haha
because we are women and we cry about everything
They're really tears of joy :)
Okay, I'm reading this thread the next morning, but here's my guess...
I noticed that they showed a close-up of Katie crying when Haeley was doing her goodbye song. My thought is that a few of the contestants spend much more time together than others, because in addition to regular rehearsals, they have to go through school/tutoring together due to their age and still being in high school. So they probably get a little more closer than others do.
Katie, Haeley and Aaron are the only three contestants still in high school, I think.
