We had a scare on mother's day. I was upstairs taking a showering as my husband was preparing to take the kids out to walk the dog. Apparently, my daughter didn't want to go so my husband thought she was going to go upstairs to look for me. Instead, she put her shoes on and went outside. She walked about half a block before someone pulled over to see if she was okay. I came down as the nice lady was bringing her back to the house. She has gone out before so I usually keep the chain lock on now. My husband forgets sometimes. Now, we've also set up our alarm system to alert us each time the front door opens.
