Now that you have the ability to defend yourself, do your best never to need to draw that weapon. Robert Heinlein said “An armed society is a polite society.” If you realize that an interaction gone awry could lead to the use of a gun, you are more likely to hold back that biting comment when someone cuts in line or takes too long to prepare your order. The most important part of situational awareness is prevention. If you don’t feel safe, leave. If you can’t leave, behave in a mild but assertive manner.
