John, I think that is normal. But, don't forget, never burn your bridges. I had a friend that left the Bureau, didn't give any notice. The job she got, did not work out. She wanted to get another Federal job and was shocked when they told her, "You are not rehire able." Plain and simple. All they can say is Will you rehire them yes or no? She burned her bridge....
Smile, it increases your face value.
