Six/River. Written for the prompt "What you call 'love' was invented by guys like me to sell Nylons" (Mad Men) from luvbarryfefe at the Merry Month of Drabbles meme. Originally posted on AO3.
River has a hard time trusting her feelings. (Or anyone's.) The Doctor is willing to wait.
River drops her lipstick. She's only half put it on and she'd look ridiculous, if he minded.
"I can't do this," she says to the wall. "You honestly believe in love, don't you?" He starts to answer, and she interrupts him. "You don't know anything about me. You don't know how I fell in love with you, you don't know what I'm planning to do. Love's just obsession; obsessed people are useful."
"Even if you were—brainwashed?—that doesn't mean I can't love you," he says.
"I'll leave you soon," she warns.
He smiles. "I'll be glad I knew you."
