"Thank you"
Severus Snape appeared in the field just behind the row of identical houses.
He walked slowly past each house making sure it was the correct one.
When he found number 7, he immediately saw the heart shaped face in the window above the front door.
As he was about to ring the doorbell, she swiftly got there first and opened the door.
"Severus? What…what are you doing here?"
"I came to…merely to see…"
Recently married, Lily Potter, looked behind her. "James is here, Severus!" she whispered.
"So, is it true?"
"Excuse me?"
"You are married to him, now"
"Yes"
He looked down at his feet with a painful grimace on his face. "I see"
There was a shout from behind them from James upstairs-"Lily, how long does it take to go to the loo, love?" they both heard laughter.
Lily walked out to where Snape was standing and grabbed his arm. She pulled him round to beside the house where a sort of alleyway was. The sun hadn't reached this part of the area yet, so it was cool and shady.
"The wedding was last week"
Snape took a deep breath and then sighed.
"I love him, Sev." she whispered.
"I…I understand"
"Lily!!" shouted James, distantly.
There was a pause, and Snape made to leave, but Lily, heart thudding, said "Severus!" she grabbed his arm again and kissed him on the corner of his mouth.
He stopped, surprised.
"Thank you Severus" she said quietly,
He then walked away, leaving her in the alleyway.

This was the last time they ever saw each other. About a year later, Lily and her husband were murdered by Lord Voldemort.
