Silence does not always mean consent

"Silence means consent." Ahhh.... these three words no longer stand what they used to mean. Why say so? I asked someone to give a quotation for a project. Ok, they sounded excited about the potential job and I was comfortable with their service. So the only thing to do then was to wait for their price to come in after discussions. One week gone, no call from them. "They are still rushing for the quotation." Two weeks gone, still no call. "Hmmm, maybe it is year end, busy busy busy." Reaching the third week..."Hello, are u guys still interested in this project?" "Oh! Oh yes! We are waiting for our sub suppliers to come back with the quote...." Ok fine, I waited again. 4th week..."I am getting pissed!" 5th week...I did not call them but guess what? They could not be bother to call me too. People, I would be a big cretin if I say I am still waiting for that quotation. For your information, they have not called me till todate. What are they doing? Playing the silent little lambs or hard-to-get? My gosh! I thought I am the one giving THEM the business! What has the world becoming?
