I grew up in a small town in which no one locked their doors. The house I grew up used skeleton keys for the outside doors which are universal. So, locking the doors wouldn't have done much anyway.
Now that I am all grown up, I have never got into the habit. I live in a fairly big town. I live in a nice home. We have nice things. I have lived in all sorts of areas and we have never locked our doors. People always think that is crazy and talk about people just walking into your home. I guess I just don't worry about it. If someone really wants to get to me that bad, a locked door will not stop them.
Is there anyone else that does not lock the doors to their home?
