Drive by shootings scare the crap outta me. I used to live in Southern CA and they were constant. Gangs were outta control to say the least, still are!
Now living in Arkansas, especially in the country gun fire shots are constant. Hunting, target practice, etc. So I've find myself not even reacting or giving it a second thought when I hear a shot fired.
Years ago I went back to So Cal to visit my brother. Him and I were out front in his yard chatting. A gun shot went off and he ducked. I just stood there with the look on my face "what's the problem?". I guess I have become numb to it??
