They are probably busy getting settled in. And now, Cody’s wife is no longer working. Before, she went to work, and he had all day to write on forums while doing whatever cooking and housework he did. Now, she is there all day, so both of them are probably busy, and he doesn’t have the free time to be posting on forums like he used to have.
When Cody gets back, one of two things are going to happen. He's either going to feel special because he realizes he was missed....or he's going to wonder why we all don't have anything better to do that try to figure out what he's doing.
