Ghost Shadow in The dark

My phone suddenly ringing and I got up. I kept my eyes closed and fumbled for the phone in
my jacket pockets. It was not there. Then I turned over to check my trouser pockets and fell
down on the carpeted floor. The thickness of the carpet prevented any serious injury. By the time I managed to get up, people all around me were laughing.
"There is a lesson in that. Don't fall asleep while taking calls!" It was Raju the Incoming- Call team-leader.
"There were no calls coming in," I mumbled.
"Calls are few during the holiday season. That does not mean you fall asleep. Utilize your
free time to read up on your manuals," said Suraj one of my team members, and always looking for an excuse to suck up to Raju.
"You ok, man?" Jay was my friend and the only person who sounded concerned.
"Yes, I am all right. I just slipped and fell," I said. The phone, which was on my desk, was
still ringing. I picked it up. The display was showing an unknown number.
"Hello?"
" Mr. Hari Singh?" the voice on the other side sounded familiar. "Yes," I replied.
"Hello Sir! Maheshe Bhai here Sir. Real estate broker."
"Yes, yes..Maheshe Bhai..tell me." I spoke in Hindi. Maheshe Bhai as always replied in his
version of English. Maheshe Shah was a Guajarati and by default, all of them got the prefix 'bhai' or brother.
"I have been ringing for some time, but you not picking up, Sir"
"Ah yes, I was .working. Did not hear the cell ringing," I lied. I could hear Jay laugh
at his desk.
