Really??
So he's loverboy?
Well, if it was me I wouldn't have even advise at all. I just let all the scenarios play right on my face why I laugh out loud. Why on earth is he loving up and down?
Teenagers in their adolescent age don't listen, they follow their emotions anywhere it leads them to. This would be the basic reason why I would not advise anyone at that stage except someone I know when I look at them they will listen.
