ewww, some tough ones:
vacation, celebrate, whirlpool, hummingbird

Our day, a whirlpool
Readying madly
Finishing day school
Leaving it sadly

Vacation upon us
Celebrate, gladly
Loading the last bus
Bus driver, crabby

Hummingbirds float by
Wings seeming frantic
Watching us so try
To not risk a panic

Days almost done now
Farewells, gigantic
Thoughts geared to just how
To make summer galvanic

(cheez! how bad was that?)

someone else give them a try...
