Work on the part of the approach that is visible. Many times a bully or a gang will approach slowly to threten and to show their power while they expect the other side to remain polite and stay as they are and on the same speed. Once the bird is scared still they start a surprise attack and get the shock to their advantage. Practice this in turns either with a threat or a simple slap and see how you feel and move as you perform either side and learn from this to handle your own speed as it fits your survival rather than polite rules of conduct that have no fredoom in them. Don’t worry too much on how you look. Think about continuing to breathe.
