Go Ahead, Make My Day…No Really Don’t

am i paranoid or just aware? when i’m exiting a building and walking towards my car the first thing i do is grab my keys. on my key chain i have two keys, which are then placed in between my knuckles. if you try to surprise me, believe me when i say you have another coming. then when i make it successfully to my car i immediately lock the doors. so what other tips do you have for me? if i’m going to do this i have to do it right.
