Now it is September
A great vacation to remember
Time went really fast
Too bad it could not last
The beach is so quiet
All summer long it was a riot
Hot humid weather
Now we need a sweater
Autumn is coming
No more humming birds 'humming'
Falling leaves are mounting
No need to be pouting
Days to next summer we are counting
