It is crude, rude and unattractive to lounge or lay down on the mat during class. Always take off your shoes before you step on the mat. Face the center of the mat and bow before you step on or off the mat. Step on with the right foot first. Step off with the left foot first.
White belts are in the rear, closest to the door.
More advanced students will sit in front of the White belts also facing the flag. Black belts will sit with their backs to the shomen facing the kyu ranks. When you hear kiotsuke become quite and sit at attention. In unison chant Om, Om, Om, Shanti, Shanti, Shanti, Om Peace, Peace, Peace. When you hear shomen-ni bow to the front of the mat.
