OK, know you haven't met River yet but who cares :)
He flashes back to when he first met his River.
"Hello, sweetie."
"River Song. Archaeologist."
"Spoilers!"
He opens his eyes to see his very beautiful wife with him, in the console room. "Sweetie? Being an archaeologist, i wondered if we could g on a little... dig, you and I?"
The Doctor can't believe it. Is River talking dirty to him? "Are you..."
"Maybe?"
"Of course, Sweetheart!" He smiles. Anything for his little archaeologist.
That one was painful; so awkward! If you don't like it, I might have to kill you.
