AA vs 10 2

Ok, this hand made me really mad recently. Not really sure what sort of analysis I can give as to how I "played it wrong" as I moved all in preflop with about $6 in a 0.05 / 0.10 game and the guy called me with 10 2. He made 2 pair by the river. He hit the 10 on the flop (or maybe it was the 2) then the other card on the river. Odds against that happening are enormous. Oh well, it happens.
