Honda: Tappet Clatter?

I have a new 2003 CR-V.
After driving in the hot climate of Southern Arizona,
so the engine is fully warmed up,
if I stop the engine for a half hour or so,
and then restart, I hear what I think is tappet clatter which stops
after a few seconds.

I assume this engine has hydraulic tappets and they are bleeding down
while the engine is shut off. I don't think they should bleed down in
a half hour.

Anyone else?
Comments appreciated.

I seem to recall reading that this is a normal sound that you don't have
to worry about--just get used to it. Eventually, you will probably not
even notice it.
