Her mum makes him park the TARDIS on their street for her entire birthday week. It rains every day, the street lights reflecting golden in the puddles, and they spend all of Friday in the TARDIS library.

She scoots closer to him at all the right parts too, and he skips a line and pronounces three words wrong.
