Are you a female teacher? Don't be angry if one day your male student suddenly acts "weird". Like falling in love with you. Realize that he just came out of childhood. In any hemisphere there will be such a "unique" event. Namely a male student falling in love with his female teacher, is common. But what should not happen is IF THE TEACHER RESPOND TO THE STUDENT'S LOVE, because the strange behavior is actually just MONKEY LOVE.
I remember when I was young, when I was just entering puberty, a transition period. It's so easy to get interested in something new. Want to try new things. Want to look full stand out, superior and full of expression. But unfortunately, ages like that often can't control themselves.
