Yes, somewhere in rural Canada, where there aren't any people around for miles and miles and he can mix potions and send red, purple, or acid green clouds rising into the air without being bothered. I think he'd be happy just being away from it all...including Lily the harping shrew. In each of the memories we see her in she is ragging on him about something. I wonder: is that really the way he remembered her? I know he loved her very, very much, but, we don't see any really happy memories that aren't ruined by her storming off in a snit about something or just giving him what-for over and over.

Missing the point much? All of the memories Snape chose to reveal involved him being in love with Lily and losing her because of her own actions. So of course we're seeing the times when she's unhappy with him - it shows the progression not only of how they became friends, but how they stopped being them (because Snape was first hanging out with, and then joining, Death Eaters).

But then, you can't expect the Snapephiles to be sensible, particularly their insistence that a scene where Lily yells at and threatens to attack James, in defence of Snape, is in fact her 'abandoning' him.
