while in the former case--the tears stand in testimony of how vulnerable your heart is to that special someone and hence proof of your love for him, in the latter scenario---the smiles stand as evidence to how happy you can be with that other someone..
so who according to you, does the 'confused' heart really love??
this post is triggered off by a conversation i had with a friend who is faced with a similar complicated situation in which the guy who had broken up with her has apparently realised and come back in her life...the dilemma ia however, due to this wonderful other guy who managed to become her friend and confidante and get her smiling even during this horrible post breakup phase..
while she is still in love with the ex, a small part of her heart is pulled in another direction---and hence the confusion!!
P.S: this is based on a real life situation and has no correlation whatsoever with "anjaana anjaani" (though we did have the conversation only after watching the movie which she, by the by, ironically found extremely 'filmy' and 'unrealistic'..lol!!)
