My son is having his friend sleep over tonight, and in the winter, it's good to have friends around. Wintertime is an indoor time. A hunker down and enjoy friendships and family time. Enjoy a new environment and create a new space indoors. There will be wall painting upcoming--an activity that will change the look of any room. Tan, dark brown accent walls, and eggplant as suggested by our friend Alexia for the fireplace.
Yes, winter is an indoor time.
