Let me sum up this book so far:

"Hi cute nerdy girl, I'm totes a non-threatening nerdy guy and you're not crazy"

 

OMG OMG OMG SAW A GHOST!  - nerdy girl

 

 

"Hi cute nerdy girl, I'm totes a non-threatening nerdy guy and you're not crazy, let's sit on this bench and discuss all the times you saw a ghost"

 

 

OMG OMG OMG SAW A GHOST!  - nerdy girl

 

"nah, cute girl, I'm totes a non-threatening nerdy guy and you're not crazy.  I like history, do you like history? Let's drive around the Boston area and look at Revolutionary War historical places and then sit on this bench and talk about all the times you've seen a ghost"

 

I'm guessing I know what happens next.  Also having trouble understanding what the point of this book is..
