Don't know for sure his problem but we all go through it .. My sons thought they had it rough, then about that age they began to get out a little and both agreed once they saw some other friends families they simply didn't realize how well they had it .. I advised both my sons to work it from the bottom up and forget the clique if it means compromise and looking down on others.. But work on being
genuinely friendly, no flattery, a simple complement or kind word , when occasions arise to those who seem to be less popular and don't pile on with the rest, especially the girls, just be kind and slowly it will catch on and they will eventually talk you up to one another and it will travel from the bottom up, be patient and pray for what you want to see and wait .. To be determined to hold to his Christian principles and convinced they are the true proper way , it is a working conscious plan and a plan in life too, to do well at all things without too much complaining, you've got to do it anyway so do it with good attitude, no need to ruin your day .. Work on it and let him be involved as possible .. The biggest fear for parents today imo is that the kids don't take on contrary spirits of opposition to the parent which could be any type, we have to win our kids too even if they have a strong foundation if resentment creeps in that's where we include that in our prayers for them and keep watch .. I pray your son can become like a mighty man of King David willing to stand for what's right and who's right to be a warrior for Jesus , that the Lord begin to give him the vision with growing strength and the comfort of purpose which is peace even in persecution .. A three or more day secret fast with prayer on your part will help you be convinced, God has the answers before he created the mountains , they are beautiful, especially from the top .. Sorry if I get carried away .
And if it comes to a fight, tell him to pick the biggest nastiest one and hit him in the stomach as hard as he can, when they don't expect it, the head only hurts your hand, I'm talking about reach up under that rib cage and as hard and deep as he can get .. Chances are he won't do it if he's a good kid but he can think about it and know the last resort .. Ha, let him practice on you a couple times but cover up if you know what I mean .. Almost forgot then tell him to go to the authority himself and confess, and why he did it and how it's going to stop with or without anybodies help, tell the trouble maker first where he's going, to report it .. And don't forget ''call my dad now''
