There are probably things in your house that would fascinate your children but you haven't thought to offer or they haven't found the good stuff yet. Consider interesting things you have that might be of interest for being old, foreign, specially made or obtained under special circumstances:ornaments
dishes / pots /molds
silverware—even one old piece you know something about
egg beater
flour sifter
can openers (“church keys”)
old bottles or other containers
old clothes from the 60's or 70's
recordings—reel to reel, 45's, 78's, 8-tracks
manual typewriter
push mower
pre-transistor radio

Speaking or writing without thinking is a little like driving a car with a blindfold. Others get hurt, we get hurt, the car gets wrecked.
When I was a kid, humans used tools and that made us human, but that's no longer "the truth." Chimpanzees can use a leaf as a sponge to gather water out of a hole. They will lick a stick and put it down a hole to collect insects (termites? ants? I don't know what). They will move things to climb up on to get something they can't reach.
If my children wake up in Albuquerque, happy to be who and where they are, I hope they can maintain that feeling every day until they wake up in the middle of the next century and look out—I don’t care what they’re looking at, whether it’s the Alps, the Rio Grande, the back of their own filling station or the White House Lawn—and they’re still happy to be who and where they are. Who could ask for more than happiness? Don’t wait. Get it today and give it away. 
Perhaps it's your computer, or phone. Chair. A nice felt-tip pen, or a lamp.
My children discuss behavior and social interactions as easily as they discuss Nintendo or their own cats and dogs. When I was their age, psychology, comparative religion and anthropology were far in my future. My kids might not have much formal terminology, but they're extremely conversant and certainly can think in those areas without knowing they're too young (by the book) to do so. They understand well that there are many versions of historical events. They understand that there are different ways to act in different situations, and with people who have particular beliefs and preferences. Some adults could use knowing that.
Usually moms find unschooling first, and understand it more easily than dads do. It does happen, though, that if and when a dad does find his way to appreciate the potential of unschooling, he can surpass the mom's understanding in no time. 
There are several sayings about the journey of a lifetime beginning with a single step and such. One step isn't the beginning of a journey if you keep one foot in the yard. You have to get away from the starting point completely.
and self esteem, when humor is an indicator of the jokester's true feelings about the wholeness and value and intelligence of chidren, that undermines children's worth and their chances of being seen, heard and respected as the full and important humans they are.
There are movies about history and movies that are history. There are movies about art and movies that are art. There are movies about music and movies that would be nearly nothing in the absence of their soundtracks. Movies show us different places and lifestyles, real and imagined.
Looking back, I think the best advice I can give parents of boys who are concerned that they might not become men is this: Consider them to be whole, no matter how old they are. Treat them with respect and find ways for them to be around as many people and situations as you can, and whenever possible let them make choices about how long to be out and when to go home; what to attempt and what to stall off on; what to start and what to quit.
Even with grown kids who could absolutely take care of themselves if I died or if they moved away, I'm still doing laundry for them because I want to free their time up to do more interesting things. I started running out of ways to express my affection and to support their interests when they had jobs and cars, but this is a thing I can still do. If I decided it was hurting me, I could turn around and hurt them. Lots of parents do that.
Recently, far from home, I was looking at a "coffeetable book" of photos of clouds. The author had included contrails. Until that moment, I had always thought of them as pollution, messing up the sky. But Holly had no such aversion to them, and without knowing I had seen them bound up in a collection of images of beauty, she took this photo one day in Albuquerque.
Some people think of play as frolicking, or as make-believe, but it can be a pervasive mood and include the way people bring groceries in, and watch movies, and sort laundry and sing in the shower. A light and playful attitude changes everything.
Can there be too little peace? Yes, and in many ways. There can be too much noise, stimulation and chaos. So finding the balance place and the comfort level is part of creating a peaceful home.
