Mr Rainbow

My Rainbow is unusual
And unique from end to end.
Her colors aren't really colors at all
But wondrous traits she spreads and lends.

My rainbow is unusual
Despite that end no one will ever find.
Her riches are not a pot of gold
But rather a wealth of every kind.

My rainbow is unusual
Because she needs no tears just to come.
She's always there no matter what
And always there for everyone.

My rainbow is unusual
Not like anything that could come or go.
Sierra is what she calls herself
But I'll always call her "Rainbow".
