What kind of fun do you have

Over my life and I suspect yours, I have come across people 

• Who look but don't see, and so miss out on life's joys and beauty
• Who listen but don't hear, so they miss out on the sounds of nature, the beauty of the thunder rolling across the sky, and the laughter of a child who has just discovered their toes. 
• Who know what they need to do, but they don't do it. So, they miss out on the joy of completing something but also feeling proud, not only of the job completed but of the effort expended to do the job.

All of these people have fun and contribute but they don't have the kind of fun that those who look and see, listen and hear, and know and do have. The latter have jumping-waving-crazy-dodgeball kind of fun.
