ok, stepping out on a limb here...... you know the, 'you might be a redneck if......." ok, you might be excused for not responding to the receipt of your swap if....... the funeral you are attending is your own.
or, you might be excused from responding if..... the bus that hit you was driven by someone else and there were no survivors.
actually, there are some pretty serious reasons for not responding. 1) you were raised by wolves.
2) the one cousin who knows how to write is still in prison. 3) the federal guvmint tore down the only post office in your state. and reason #4) the tinfoil on your head has developed cracks and all you can hear are the aliens phoning home.
