definition poem

you look beautiful for some people but boring to children 

you make me tear up when you grow up

but not in a good way

and when you die that means the sky becomes grey

you have so many colors but not any thing makes you feel grey

i can find you siting on the grass 

with all your tiny friends or the ones that are 8 feet taller 

your beauty makes me feel calmer
