James & Lily in the Mirror of Erised

[Kristin]

Although I still have other issues with this scene a thought occured 
to me late last night.  

Harry has never seen his parents in photographs and the Dursley's 
certainly didn't talk about them. The only thing he does know up to 
this point is what he's been told by people in the wizarding world: 
he has his mother's eyes and that he looks like his dad.  So maybe 
what he sees in the Mirror is what he imagines his parents to look 
like if they were still alive. This could explain the age difference, 
they would be in their 30's then. Just a thought. 

Cheers,

Kristin
