I just caught myself doing this while responding to another post. I talk and think like I'm still at home and still part of the family. And this wasn't the first time. Earlier this week while talking with some friends at work, I mentioned something that would happen at home and my friend helpfully reminded me that it doesn't matter anymore because I'm alone now... my response "oh, yeah..."
I thought by now I would be used to the new arrangements, I am trying to make this place more "mine".
