I admire John's eager love for the beach, the ever churning ocean waves, and the recklessness of swimming to far out islands and buoys barely visible from the sandy shore. A wildness comes out in him at the beach, when the sun is high and hot, the water cold and rushing up past your shins. He's extremely playful like a Labrador set free in a dog packed dog park, but I was so timid and downright terrified when first standing in the damp, cool sand.
I don't believe it is any surprise as to the inspiration of today's poem. I don't know where you live but it is the dog days of summer here in Oklahoma, triple digits every day. Today is a high of 111F, not the "feels like" mind you, but actual Fahrenheit temperature.
