What was Luna going to say?

I did remember that DD talked about the locked door, but amid all 
that waffle, he never actually says what it contains. (I sometimes 
think it would help Harry considerably if Dumbledore was a little 
more straight-forward with him.  Why not just tell him what was in 
there?) The general consensus seems to be that it contained Love butI 
should still have liked to know what Luna thought. I also wondered 
about Ravenclaw Bookworm's point that Luna and Dumbledore might not 
have been talking about the same locked door.

to have thumped her)
