inertia!

There are days when this state of inertia overcomes and all my senses seem to be dead... i listen to music regardless of the fact that its absolutely not soothing to my ears, to my mind...the surrounding is so monotonous, the daily routine is so stagnant but i dont feel anything any more... today is certainly one of these days when i am working but i dont feel it, i am talking, listening to music, but not sensing anything... !!!!
