True, but you know which noises are normal for your Civic much better than your new mechanic (or even your old one). If you know there's a new sound, your mechanic has to take that as truth and find the (a) problem. Works the same for a body.

Incidentally this problem is what is stopping me from going to a doctor right now. I'm having headaches recently which are not normal for me, but are still in the realm of "normal". I'm putting off a visit to the doctor because I'm afraid they'll say it's normal. It is not, for me.

Also, always search a second opinion. I wouldn't be born if my parents went for the "absolute truth" of the doctor they had at the time.
