not sour grapes

Saying "I didn't want that job anyway" after you didn't get it is usually a case of sour grapes. But in the case of my recent experience, new information has come to light: that department is going to be moving its offices to Long Island City. A commute that involves going over the Whitestone Bridge and taking the Long Island Expressway during rush hour.

Boy! am I glad I didn't get it after all.

Granted, they aren't actually moving for quite a while, but still.
