When I first moved out I invested in just a simple locking door handle with key. So when I am gone I can lock it and not worry about anything. Though after going through 3 roommates consisting of family and other people I have met. I decided I might as well pay the extra $300 myself and enjoy living by myself. That way I don't have to worry about being caught wearing diapers except by my BF if I choose to wear em. Or have a messy place because everyone else is to lazy to clean up after themselves >:C
And of course have something you can hop into quickly just in case you like to wear just diapers. Since a roommate or someone else could possibly want or need you for a quick moment. So its best to be ready to hide your diaper if necessary at a moments notice.
