How CouLd You Do THiS?

How could you do this?
How could u sink so low
watching all the kids grow n grow.
This is surely something to show
this is something my parents both know
you try to hold on
you try to fight
you think that you have all the might
but in the end somethind inside gives you a fright
that someday we'll all be out of your sight. (this was a poem i wrote to my grandparents after i thought they had lied and got my siblings and i taken into foster care)
