With sadness still lingering within him and have no way of dealing with it, it slowly forms into anger and regret. Having thinking only one way to deal with this is to to take it out on someone else. Starting fights with local tough guys and purposely pissing any guy he wants to brawl.
No more nice and cheery. Not while anger is building up.
Besides, nice guys don't get what they want. He learned that the hard way.
