MonoMad - Monday - Macro ~ I'm Home!

The sound of a key in the door can be one of the greatest sounds in the world. To a child or a spouse, it can joyfully signal the arrival of a mother or father, a husband or wife, who's been away for the day, or longer. When you're a teen, it could be the signal to put something away, or to have your boyfriend or girlfriend straighten their clothing. Sometimes it's you putting the key in the door after being away on a trip or just a hard day at the office. What will that sound mean to you today?
