"...because I did nothing wrong during the year". Yes you did Massa but it was indeed nice and mature of Hamilton to come over and chat with you anyway.
Nice move from Hamilton. Massa is way to petulant to make such a move himself, since he can't admit his own role in the clashes. Good thing Hamilton took the opportunity while he could - it won't be long (1 year max) until Massa isn't in the paddock any more. A new record, Massa is the first Ferrari driver since the dismal, dark days of 1992 to finish a season without scoring a podium.
Hamilton has the most to gain with burying the hatchet with Massa, makes sense, respect to him for making the effort.
