My doors are never locked when I'm home & awake, not on purpose anyway. There are always too many kids running in & out. I love that we have "that house" where most of my daughter's friends can still come by and just walk in the door. The boys are still a little young, but my middle kid is starting high school in Sept and I think that will change. I love that my kids' friends are comfortable in my home and the door it literally always open for them.
