This rule is RIDICULOUS!
I see nothing wrong with hugging one another. Hugging is a way of actually showing affection. The principal thought that it was an alternative to kissing, which is showing affection as well. so she freaked out and banned hugging. Apparently she doesn't want love in her school, and even if she didn't ban kissing, students will most definatly start kissing eachother to show their anger about the hug ban issue. And if she banned both, everyone will start winking at eachother, and to ban that she is going too far, and needs to be stopped.
Anyways, what I am trying to say is that this principal has no morals what so ever. Hugging never is/was sexual (if it was, no one would want to hug their mom!). If hugging to her is a problem, then she is the only one with the problem. END OF!
God.
