My parents instilled in me "when you leave the house, take your keys and wallet."

It has served me well. When the kids were teens, I'd tell them "take your keys". The best part was when they'd get home from somewhere and not have their keys and would either have to call to wake someone up or would break a window to get in when no one else was home or was going to be (that was my favorite, now I have to fix a window because you didn't do something basic)
