Maybe she was day dreaming and was staring at you and didn't even notice... Maybe she is just thinking there can be a lot of reasons. Also depends how she was looking did she seem confused, interested, etc.. Finally she could be a creep and thinking about how she is going to kill you just kidding.. I don't think you should worry about it might of been nothing :).
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.
