Summertime snow

In the sun, My skin gets darker, But that is not my fault, The heat, Makes people uncomfortable, But that is not my fault, Kids play with water, As though we have some to spare, But that is not their fault, Because we allow them to, Youth is important, Yet mine is fleeting, But that is not my fault, A little bit of snow, Took my brother away, Snow in June? That's not my fault. Something white, Like glass, Has snatched him away, Yet he still stands there thin, And smiles, He acts like it's not his fault...
