We propose that the observed stiffening of the shear modulus with decreasing temperature can be well described by a viscoelastic component that possesses an increasing relaxation time as temperature decreases. Since a glass is a viscoelastic material, the response functions derived for a viscoelastic material are identical to those obtained for a glassy component due to a time delayed restoring back-action.
