This morning I was sitting on the loveseat in the living room when my son woke up. I had heard him get out of bed and was waiting for him to come out of his room. He came to the doorway of his room and peeked ever so slowly around the corner until I acknowledged he was there. Once I had said good morning to him he came running over to me.
One of the first things he asked was where his sister was. When I told him she was at school his response was, "What? I need her." He was sad but quickly got over it. I think it dawned on him that sister wasn't home which meant he could go into her room, which he immediately did to get some of her toys to play with.
