"That boy found it! You and that boy have been 
sneaking in my room!"
"No--not sneaking--"  Now Lily was on the defensive.  
"Severus saw the envelope, and he couldn't believe a 
Muggle could have contacted Hogwarts, that's all!  
He says there must be wizards working undercover 
in the postal service who take care of--"

So, Severus was in Lily's house at least once.  Going 
by what little we know of the Evanses who seem to have 
been even more wizard-friendly than the Grangers 
(thrilled to have a witch in the family, passing 
through the barrier onto platform nine and three-quarters), 
I can imagine that he was made welcome in Lily's 
house, probably even fussed over by Lily's mother 
(poor little urchin).  I doubt if Lily ever went 
to Sevy's house, though.

The memories we saw cannot have been the whole story. 
They must have summarized Snape's regrets, the memories 
of his offenses against Lily that tormented him.  Surely 
they had fun together, too.  Why would Lily have 
remained friends with Snape to the end of their fifth
year at Hogwarts if it had been nothing more than what 
we saw, Snape making bungled attempts at friendship and 
Lily merely tolerating him.
