Some of you anti(s) may think that "Sasuke was never grateful for Sakura" or something like that.

Well, he is grateful for Sakura. Sasuke was also grateful for loving him and for protecting him. He also returned that by saying one word thr night he left the village, "Thank you".

As I said, he said that for all she had done. She had always protected him, loved him and cared for him.

When Sasuke had left the village agian, but not to seek revange, he poked Sakura's forehead and said "Thank You" one last time.

The forehead poke and saying "Thank You" agian was his way of showing his love and affection to her.
