Dumbledore's / Harry's "not really" comments

[nancy cleaveland]

OK, I'll come out of lurkdom to ask a question. I searched
the archives, but it's hard to search for "not really." <g>

At the beginning of PS/SS, Dumbledore says, "There, there,
Hagrid, it's not really good-bye after all," when Hagrid is
sniffling as baby Harry is left at the Dursleys' front door.

At the end, as the trio is getting on the Hogwarts Express,
Hermione says that it feels strange to be going home, to
which Harry replies (looking back at Hagrid), "I'm not going
home; not really."

Could there be more to this than I'm reading into it, or is
it just a coincidence? I mean, I know that Hagrid will see
Harry in ten years -and- that Hogwarts seems more like
"home" to Harry than Privet Drive. Neither statement is
canon, but I started to wonder after noticing the lightning
bolt wrinkles on Dumbledore's forehead in the hospital
scene. I'll also admit to thinking that Dumbledore and Harry
were one and the same during my first reading of SS, which
is probably why this jumped out at me in the first place.
