Entering/Leaving A Room

Bow if you can or gassho (palms together) and not attract attention, or simply bow your head slightly. If not, pause and mentally bow. If there is a door, notice the door handle and the turn of your wrist as you open it. Notice the door jamb. Touch it. Notice which foot you cross over the threshold with first. Choose which foot each time. Do it the other way next time. Notice when you leave once space and are fully in the other.
