What the seasons mean to me,
It’s everything that I see.
I learn about it all around,
The fact that seasons astound!
In March, my floral bell rings,
Specifically, on the first day of Spring.
In June, I go “Hooray!”
Because it’s Summer’s first day.
In September, I go “I Love it all!”.
Because It’s the first day of Fall.
In December, I try not to squinter,
Because It’s the first day of Winter!
What the seasons mean to me,
It’s everything that I see.

I changed your ‘bummer’ word to something I hope is a bit better.
