I can confirm this, the girls in my class touch each other all the time, so much that im not even surprised to see it at lunch time
Now that you think about it, I remember my highschool years, so many naughty girls there touching eachother.
They even kissed eachother once, it was so weird, and none of them were official lesbians, so it's strange
And in numerous cultures, men hug and kiss each other on the cheek when they meet or part.
Gestures of affection are simply not clues to sexual orientation.
I know, we do that here all the time, and I`m not gay.
Its a kind of gesture of respect and friendship. When you kiss a man on the cheek it means that he is almost in your family, and very close to you.
But when women touch eachother, they dont do that because of respect or familiarity, in fact women hardly show any respect to other women, because all women are esentially deadly competitors for men.
Women do that because either they cant find a man, and choose to become lesbian, or they just want to impress other men by their sexuality.
