The first role was the woofer. Woofer is a term used to describe the attacker. Attacker implies physical violence, but the woofer only uses his voice when threatening someone. The next role-player was the coach. This person stands behind the victim, and supports the victim throughout the attack reminding him or her what to do when attacked.
Spatial awareness is another important concept in self defense.
Meza explained that spatial awareness is learning how close is too close in terms of physical space. To learn about this, we needed to learn how close we would allow a stranger to get before invading our personal comfort zone. The first exercise demonstrated how a person reacts to a good friend in terms of personal space. We got into two lines and came up to each other as if we were best friends, who had not seen each other in a long while. In this case, we all allowed the friend to get very close, with hugs, pats on the back, etc.
