This is a clear demonstration that you do not understand resonance.

Aint that the truth

Wow indeed...

Now _my brain_ is hurting from reading this foolishness.

The guitar string is self-resonant, just like the wine glass or a tuning fork or a bell.  The air around the string drains energy away from the resonating guitar string in two ways.  The moving string is pushing its way through the viscous air and therefore there is friction.  The moving string also couples energy into the air in the form of sound waves.  So you can simply say that the air is damping the resonant string and draining energy away from it, like a resistor in a parallel RLC circuit.

That's why I said you have apparently been bluffing your way through this.
