show you,show me or show it to me

The sign for show is "directional." By that I mean you can use the direction of the sign to indicate who is doing the showing and who is doing the seeing of what is being shown.  For example, if I start the sign away from my body (nearer to you) and then move the sign closer toward my body (nearer to me) that would mean "you-SHOW-me" or "show it to me."
