Make yourself a good hand. Don't wait to be asked, just jump in when you see a need. Wash a dish, make a bed, change a tire, help out a friend or a stranger whenever you can.
Start “home economics” school with them. Laundry, cleaning, cooking, how to change a diaper, comfort a baby, soothe a toddler, what's involved in caring for pets, budgeting for food, keeping track of maintenance schedules for humans, pets, cars and machines. Engage with guests, be a good host, etc. Know when and how to tell someone to GTFO of the house (racist or misogynistic speech, etc.) Every kid needs to learn the art and science of home management. Look for and point out examples in books and movies of good home science skills.
Learn the difference between keeping secrets and keeping some things to yourself. Never kiss and tell. Err on the side of saying less rather than more.
Roll-play confrontational situations so they can practice staying calm, not reacting in situations like road-rage, bullies, being screamed at by a boss or a customer.
Put him in charge of figuring the tip out when we’re out at a restaurant. Calculate 15% or 20% etc. Also emphasize that the difference between a good tip and a great tip is usually just a few dollars but it makes a difference to the recipient. Be generous with people who are in service professions.
Be protective, never be possessive. watch out for your friends’ well-being, their good names, that’s what friends do. But friends don’t try to manipulate someone’s feelings, thoughts or actions.Same goes for romantic relationships.
Alka-Seltzer is great for a hangover or even better, take it before you go to bed after partying. Disclaimer I’m talking about a few drinks. For the love of everything holy, please don’t ingest insane amounts of alcohol at a time. Buzzed is fun, drunk is stupid. And dangerous. Never drive once you’ve had a drink or weed.
For a bad cut / gash, use a rolled up washcloth or hand towel to apply pressure until you can get to an ER.
If you have to drive yourself or need your hands free, secure the towel in place with duct tape.
