bullsh**, sakura waited for someone who tried to kill her several times yet it worked wonderfully for her and the only reason shes with him right now its all thanks to naruto.
You know, love works out in shoddy ways sometimes. This happens in real life too. People wait around for those who wouldnt bother coming to their funerals if it meant missing their favorite daytime talk show.
But Sasuke admiring her forhead is unnecessary salt in the wound. That was Something Naruto liked about her. He could have written SS without adding that bit in.
