Just put your right hand over your chest. Move it in a clockwise motion (from the observer's point of view) using a circular motion a few times.
Forgive me for being late in my post today. I really am "Sorry"
The same as Please, only with a closed fist.
Take your dominant hand and touch your fingers near your lips with a flat hand. Move you hand down and in the direction of the person you're apologizing to.
