It's the little things
Growing up I shared a room with my older sister until I was about 8, when we moved and I finally got my own room. I remember how ecstatic I was to finally get my own room, but I also often found myself just kinda hanging out in my older sister's room a lot too. Well, when she'd let me anyway.
Not every kid can have their own room, and many of us survived sharing with older siblings and many of our kids also have to share with siblings, but one mom's recent post to Imgur about how she finally gave her son 'his own room' will break your heart (in a good way) it's so sweet.
