He curled up in a ball in bed and tried to go to sleep. Within half and hour he got up, dressed and made his way to her room, hoping she'd be there. He knocked on the door. No answer, so he opened it as quietly as he could and walked in. He called her name and was surprised to hear her sleepy voice in return. He reassured her by saying who it was and sat down in her rocking chair in the corner of the room. He felt he needed to talk with her after seeing her with that volunteer. He asked her what she'd done after they'd separated at the party.
"Who was the guy you were sat with?"
"Just some volunteer. He's really nice to talk to."
He was still feeling drunk from the vodka and he let the conversation take it's own path. After some time he got back round to the topic he really wanted to talk about - the guy who she'd been sitting with. He remarked, jokingly, that he could see something happening between her and the volunteer.
"No way. He's much older than me. Even if he was the greatest guy in the world. He's almost twice as old as me."
He thought that was an odd thing for her to say, him being older than she was. But, as she'd said, he was almost double her age. He left the room without saying much more and apologised for coming so late.

She came round the next day, seething with anger at his actions in the early hours of the morning. He didn't know what to say but eventually got his point across, justifying what he'd done. Once more she told him nothing was going on.

He'd have to take her word for it, although he wasn't completely reassured.
