I know it's my own stupid fault, but I seem to forget to pick up my transporter stone again upon re entering then area I started from.

I have a stone at George's shop that I leave there. So I carry another stone with me. When I want to return to Georges, I use the "drop and use" stone command. After I am finished with my business at George's place, I click the stone that I keep at George's to return to the original area I started in. But many times I forget to immediately pick up the stone upon returning to the original area. Then I go off and do something else and totally forget where I left it. Am I doing it wrong? Is there a smarter way? Thanks
