The best success story out of your family Nino is you had a really cool Dad growing up.

Now, u have repeated that process cause your kids have a cool Dad who has arcade and pinball stuff everywhere and your own factory now as well like your Dad before you.

It is great that history has repeated. Your kids will have kids and they will be around your pinball stuff as well.

A family tradition as such that has been going for fifty years and will go another fifty. It don't get better than that.

It's also nice your wife looks after your Dad. That's great karma and the best payback a son can give to his loving Dad.
I am sure your Dad is real proud of APR.
