We can choose our age. We can be as childlike as we want or as ‘grown up’. We can play whatever side of us we want to. Society has conditioned us to think if we are young we are free and when we get old we become tied down.
It’s actually the opposite. Maturity brings experience of what makes us feel good or not. That’s ultimate freedom from age. So go play on the swings or fly a kite. Or sit in a rocking chair.
