Ask yourself this . How many of you have outside lights on @ night, on motion sensors, or automatic on/off units. How many of you keep your garage , front, side, back doors open on hot days / nights? How many of you use the garage door opener, pull in to the garage, then get out before the door closes behind you? How many of you, Spouses incl, look in the back seat before getting in the vehicle ? How many answer the door for someone you don't recognize?
Based on past threads it's a lot.
Safe, secure, alert is all well and good outside the home, If you don't practice those same precautions at home, you've acomplished nothing.
Myself, i'm pitiful when it comes to being alert, sometimes. It's those times my brain says. You're lucky this time.
