Love to those at a remove from the hurt, but who still hurt because it's the empathetic thing to be.
Love to those who are dealing directly with loss. Love to those helping those who are dealing directly with loss. Degrees of separation: it deserves to be remembered, and respected.
Also...find our calm. Do not leap to conclusions. Let those who are learning why this happened find some answers. We will know more. We will deal. We will cope as best we can.
And still...love to Boston.
