@levisan I live alone, and no one has a key to my house... so my answer was obviously no but im not sure im the audience you had in mind.
@freemo I thought of the question while sitting on the toilet while the wife and kids were gone, and realising that I had habitually closed (but not locked) the door behind me.
I suppose your habit-training levels are very different!
@levisan This is probably TMI but i literally dont close any doors in my home except for AC reasons, and am almost never fully clothed when in my home since I literally have no motivation to get dressed :)
