Blood wont change

You may think,
Yours is the updated house,
Among the rest.
You may think,
Your siblings, full of love
And compassion, are the best.
You may think
Your parents, are alike
Their counterparts.
You may think,
Your home will be untouched
Of all earthly things.
But,
A day will come
When your conceptions will be shattered.
Blood attracts blood,
It never leaves its traits.
No one, neither you home,
Neither your siblings,
Nor your blood is different.
