Well assuming you are a male. It tends to be a indicator that she may "like" you. However you could of had something on your face or she may have been simply been drifting off and your lips were the first thing her eyes settled on... But I would assume it means she likes you :).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
