For Christmas Travis and I decided to only exchange stockings this year.
One exciting suprise in mine: a peep hole.
Our front door is armed with an ironwork door and your standard wood door. The ironwork door is great to have open for light, but not something you always want open. The wood door lacked a peephole; not always safe when you are home alone.
Thus, a peep hole. It wasn't a huge undertaking to install, but it's usually the little things that are most exciting.
