 This scene has always sent a Red Flag up in my mind--it's a thread
that I plan to trace one of these days.  In any case, the fact that
JKR brought it up says something--ie, there's still something about
those Dastardly Dursleys that has yet to be revealed. 

now Eustace_Scrubb:

Could there be a connection between gifts of Vernon's old socks and
the fact that Dumbledore sees himself holding socks in the Mirror of
Erised?    "One can never have enough socks"...hmmmm

Cheers,
