learn well! if she's away from knife, have a tears, etc, doesn't mean you're safe! in fact, the danger might not be to you personally, but to anyone around you (as proven with number 3 and 7)!
that's why, if you're popular with girls.... STAY AWAY FROM ME! I don't want to be on the receiving end simply because one of your girls is jealous towards me!
