I've seen this Thai teenage male problem many times in my estate. From the day most Thai males are born they are spoiled out of control by their grannies when their parents go to work. By the time they're school age they are totally out of control and can throw all sorts of tantrums when they don't get their own way. Once they are teenagers they hang about with others their own age group so they then have total disregard for the law. Only yesterday a youngster opposite our soi was bashing his head into a concrete wall, all because he locked his keys inside where he lives. When I approached him he was showing his teeth and snarling like a wild dog. I've seen him behaving like this several times. May I add he goes to university and was awarded a Kings scolarship, so it appears that most young guys have same lawless traits.
