100-word fiction: ‘She smiled’

She was sat two seats to his left and he could tell she was doing that self-satisfied smile. She wouldn’t say anything more now; everything had already been said. First had come the sly criticisms, tempered with a few jokey remarks. A day later she said that nothing was meant, that they were still a team: he had her support as always. It was supposed to put an end to the matter but there was no way it could be forgotten. He wanted to tell her to leave but it was impossible. Either way, they both knew it was over.
