Ok, the Gf is flying in to come visit me. And her flight is going to arrive early in the morning, like graveyard shift hours. After a long flight, i am sure she'll feel tired, so I want offer her a nice, relaxing bath if she wants. I have been looking at bath and body works. And I am heck confused. I see things such as body washes, body gel, body scrubs, bubble bath, bath soaks & salt ... and I have no idea what any of those things do. What exactly do I need for a nice, relaxing bath? Would someone be kind enough to help out?
