Things are rarely black and white. Most situations (and all people) are complex. A nuanced approach is necessary to understand them. You can’t learn - or love, if you’re judging.
Be yourself. No need to pretend to like something the crowd is doing. Half of them are probably just as unenthused as you are but are afraid to say so.
My dad was a Marine. He enlisted at 18 with his buddies during he Korean War. He was never a "typical" Marine, always a gentle spirit and rarely spoke about his days in Korea.
One carry-over was kind of a little inside joke he had with his buddies in the war: They used the expression "Semper Fi" sarcastically, in the opposite way it's meant. When they said it to each other it meant "I got mine, you're on your own. Fend for yourself." We always used to joke about it too when little things happened like there was no more milk for the cereal, "Semper Fi." Of course the irony is that my dad and his Marine buddies were the very definition of faithful when it came to the big stuff. They just liked to joke about the little stuff.
Still use it jokingly that way to this day.
Curate a presentation on heartbreak. Talk about heartbreaks endured by people we know, fictional characters, historical figures, etc. Point is to normalize it, prepare them for it and teach them that they will come out the other side.
Put a few drops of tea tree oil in their shampoo bottle to keep lice at bay. If there’s a outbreak at school, add more. (Or spritz their hair with a tea tree oil solution.)
***Manners!! *** Etiquette is the secret sauce. Everyone appreciates being treated with respect. Etiquette is the art and science of respecting others. It’s timeless and universal. Customs change, hence the need for constant study, but respect is always the foundation. In summary: Be nice. Start with yourself. Study etiquette. It will help you in every single interaction you have, social, professional, financial, everything. Manners apply to every human, in every interaction, even on the hard days. Hence, the need for practice.
Puberty is like putting a 12 year old in the pilot seat of a fighter jet. A total sh*t show at first, then better but still erratic and dramatic until they really get a feel for the speed and the pressure, the gauges, etc. They’ll learn when to question or to trust their instincts. Tell him that he’ll fly this jet for the rest of his life and it will always be dangerous because it’s an effing jet, but he will learn how to fly it expertly. He’ll do good, have fun, accomplish missions and refuel.
