A gun is just a tool, good to have around but your chance of needing it (depending where you live/go) is low.
I've gone unarmed before and didn't overly worry about getting caught in a mall shooting or a driveby, etc..
But I bet you would have felt really bad if you had posted this under the title "I was Unarmed.... and almost didn't Live To Tell About It! from the hospital bed
I don't think that most here are that worried if they forget the gun when they go out, like I said, it's a nice tool to have around just in case but normaly the chances of having to use said tool is low (depending on where you live and areas you go).
Plus, you had your wife with you, she would have kicked anyones butt that tried to mug/rob/kill ya'll
