Bosom Position - Guests reclined on their left side with a pillow supporting their left elbow, leaving the right arm free. Usually three persons occupied each couch, but there could be as many as five. The head of each one would be on or near the breast, or bosom, as it were, of the person behind him. The person with no one at his back was considered in the highest position and the one next to him in the second place of honor. In view of the nearness of the guests to one another, it was the custom that friend be placed next to friend, which made it rather easy to engage in confidential conversation if desired.

Well, I'm glad Watchtower cleared that up. Carry on Bethel Boys.
