As Severus was leaving, they stood for a moment at the front door.
"Come back," Harry invited. "Come for Christmas."
"It won't be anything special," Harry said. "Mostly just you and me."
"No Weasleys?" Severus asked.
"It's... complicated," Harry admitted. "I'm welcome, but, well..."
"A story for another day," Severus let him out of explaining gracefully.
"Unless you have plans," Harry offered.
"No, I do not," Severus agreed. "I will be glad to come for Christmas."
They stood there for another moment, waiting. Severus briefly wished there was mistletoe so he'd have an excuse to kiss Harry.
