I am blessed to have a not small walk-in closet. It isn't the biggest thing, but it is adequate. I am not talking about just clothes here. I have four small bookshelves in my closet--every one packed with books. Books I had in divinity school. Books that I have acquired since divinity school that are sermon helps. Books I just want to read because everyone else is reading them or they sparked some interest in me.
I have a giant floor pillow to lean against, and I can just read right there in my closet. It muffles the sounds of the rest of the house. It is a place to think, but mainly it is a place to get away into the world of a book. Getting caught up with the characters, and forgetting that I'm even in my closet.
When my husband and I have a disagreement, I sometimes escape. Sometimes, particularly after school, I go there to escape my boys' whining. They all know where to find me, but I think they realize that Mama needs a time out sometimes, too. Sometimes when my oldest son needs to read his book for school, he gets to go to my closet. It may end up being scared space in the house as we search for a place to pause and think and read and dream.
I designated my half of my closet as my own place in the house. I think it is very important to have a place like that. Silence is good. Self-reflection is good. It can bring renewal.
