>>No, I don’t see any indication that they were upset with Him.<<
Let me point it out specifically: “And his mother said to him: Son, why hast thou done so to us? behold thy father and I have sought thee sorrowing.”
Now, back in the Jerusalem of Jesus time everyone spoke in King James English so it needs to be translated into modern English. Let me take a stab at it (although this is only my interpretation):
And his mom came up and said, “son, why did you take off without telling us where you were? We’ve been frantically looking all over for you. We were worried sick.”
They may have even been planning on grounding Him for a week.
The point is, they were treating him as a parent might treat any child that took off without telling them where he was going. That at least implies a certain “normal” relationship between them and Him.
I haven't posted anything from the KJV.

This requires you to reach a conclusion that Scripture does not support.
