Sometimes My Heart Feels

This is a poem I wrote when I was in Writers' Club.
This was when I was in 3rd grade.
The poem's title is called Sometimes my Heart feels.
At the time I wrote this, I recall that we were learning how to write a 'killer last line'.
So as you can notice, at first there is a pattern of how I wrote this, but later at the last line that changed and I wrote what I could to get close to that killer last line.
Please tell me what you think of this poem through comments!

Sometimes my heart feels like a kid groaning because of

too much homework.

Sometimes my heart feels like a balloon popping in the

park.

 

Sometimes my heart feels like a hummingbird

 

twitting from flower to flower.

 

Sometimes my heart feels like a pencil breaking.

 

Sometimes my heart feels like a present waiting to be

 

opened.

 

Sometimes my heart feels like a hamster scampering in

 

circles.

 

Sometimes my heart feels like autumn leaves swirling in the

 

sky.

 

Sometimes my heart feels like a pancake flipping in the air.

 

Sometimes my heart feels like a rose blooming in spring.

 

My heart has been thoughtful all of these

but it always is the lake reflecting the rainbow.
