  For Gamma-Ray Bursts occurring in dense star-forming regions, the X-ray
afterglow behavior minutes to days after the trigger may be dominated by the
small-angle scattering of the prompt X-ray emission off dust grains. We give a
simple illustrative model for the X-ray light curves at different X-ray
energies, and discuss possible implications. A bump followed by a steeper decay
in soft X-rays is predicted for bursts which are heavily obscured in the
optical.
