I truly apologize but I don't feel comfortable writing your whole poem, I just feel like there would be consequences. However, I will help you out. Like I said the poem would be about Summer. And since it's 6-8 lines, it would be short. So it should go with something like this.
As I walk down the boardwalk,
The beauty of it leaves me in complete shock.
The sun smiling down at me.
Fills my spirit with glee.
I really hope this helps! Once again, sorry.
