Another important note is your state of mind. If you choose to protect the status-qua than you are defending the air and not yourself and are at a disadvantage. Have a mind to avoid sparring for sparring. Fighting when you cannot avoid it is done to stay alive and to stop fighting. Think about it.
Have a partner walk around you and come to take you down and take your wallet when he feels secure in entering your second distance (stand a pace away so you can touch without stepping in) your job is to be where you are comfortable and listen to comfort and discomfort in your body and mind and work with them but not according to them. Keep all your faculties working and remain calm by being aware of your breathing.
