Leaving the door open

Yesterday I was talking to my supervisor about my new job and she asked if I would want her to contact me if a similar job opened up at the agency. Of course I said yes! I really would like to come back to this agency again. I've worked there in the past and know quite a few people. It's a really laid-back and friendly atmosphere. Plus, the benefits are the best that I've ever even heard of. I mean, they PAY their employees health care premiums! I'm so glad to know that they would want me to come back. I was scared that I would be burning my bridges by leaving!
