I’m sitting at my computer when the world grinds to a temporary halt. I stare at the screen trying to make sense of it with a scrambled brain and pounding heart. Linked In, of all things, has been the cause of this suspension of reality. It seems like hours but is probably less than a minute. The rest of the screen reduces to pixels as the message throbs at me. My mouth has turned dry and everywhere else is sweating. I’ve had contact from someone who is probably my half-sister.
