Once you are responsible for children, you gain skills you weren’t aware of before. For instance, after our son was born, my wife and I developed a keen sense of what makes a well-designed playground. We became critical of landscape architecture!
We realized we had preferences. Does the park have clean and accessible bathrooms? Are there enough places to sit? Is there a green space for games and unstructured play? Are there areas for both older and younger children to enjoy? Does it provide a sense of variety and adventure? Childless adults rarely ponder any of this.
