Where?

Sometimes I wonder where I belong in the workplace. Since moving to my new position, I don't seem to 'fit' anywhere. The girls up front have their little cliques, go out shopping, to concerts, etc. The girls in the back that I used to work directly with are going out also. Guess I just feel a little left out, they were talking about what a good time they had last night when they all went out bowling. I never got even an invitation. I couldn't have went anyways, but an invite is always nice.
On another note, while at the pool for a birthday party Missy was invited to, I was invited to a Labor day cookout by another mom. Progress? I need some social interaction with adults. :)
