That Distance

People have notion from dishonest practice about their abilities that can prove fetal. Working in high speed on a low speed simulated attack or working hard against a complaint partner results in allusions of abilities that do not match what will happen if someone does not play by your rules. Have a partner with an open hand stand a step from you and have him place his hand on you where you work to avoid any contact by him. Do this from several angles from your body and see if this little drill makes you think of your ability to avoid being cut or stabbed (big difference!) Being swift and strong may not be the way to go when a deal changer like a knife or a sharp shard of glass is about.
Advance to standing and having a partner walk perpendicular to your station and have him again not reach out but while walking move his hand and touch you. Again mark your notes on the fighting from a stationary place and keep breathing.

A gentle reminder. A cut in the hand is a prolog to a stab in the torso.
Be safe and keep your shield up by paying attention and being honest.
