Would you be pissed if you were being moved from an office to cubicle?

My boss told me today that I might have to move from my private office to a cubicle in order to make room for new people/ department moves. Apparently I was only in an office because it was free at the moment and my position doesn't require one, yet there are people in the company with lower positions that will keep theirs. I've been at my position for almost a year now and it feels like an insult.
