Need help on writing a poem about childhood memories?

I can not write for my life. I have to write a poem about my childhood and have no clue what to write. Could someone help me or write me a poem about childhood memories (it can be about whatever, but not that deep).

Each limb of the sapling is frail
Incompetent of acquiring sunlight and rain
The sapling is gradually withering
It can not abandon it's home
The sapling must not perish
It strives on, tenaciously.

It was victorious
Now it stands tall
In the middle of the forest

Sinking Sun

That fleeting thought is gone, well most of the time.
You see, it's hard to say that I've not lost my mind.
It's been burried beneath dust, piled high;
and the pile just stacks higher the more reality is denied.
And the days moving forward yield absolutely no sign
as to whether we fall or whether we fly.
But from the looks, it's safe to say we've reached the end of our flight;
as the sinking sun turns day into night.

I imagine a pretentious douche riding on the back of a local boy or girl through rough terrain while he watches... a poor gazelle who hasn't eaten as much as the rest of the herd because of the nights spent searching for her youngster who wanders away to play and explore but whom she loves too much to forget... I imagine that douche cheering as an alligator pulls that love-weakened good mother gazelle into violent ripples of water where she dies; that douche who hunts zebra with an elephant gun as tall as himself mocks that mother gazelle's weakness as he watches, and does the same when the gazelle's playful child gets lost waiting to find his mother who never crossed the water and the child's throat is torn open by some hardened killer lion without a pride.

That's what I imagine anyways. The writing of the couplets was absolutely brilliant. Most writers angrily think like those lines, at some point - thoughtless criticism is abundant. I wonder, myself, what makes sense, sometimes.

Smart, entertaining, poetry for 6th graders?

Hey my little sister wants to get into poetry, but I'm having difficulty finding poetry that doesn't sound "for children" (her words not mine) like Shel Silverstein and such. She is in 6th grade, pretty smart (H student), and would like something funny/ sarcastic, but by someone well known. Maybe something like a toned down Dorothy parker? I don't know. I want to veer away from Shakespeare and poets that use antiquated language.

Feel no sorrow, is this a poem?
