Ted made up his mind to call that woman back. At least leave her a message and admit he didn't remember owing anybody dinner. What could it hurt, really.
"You seem very confused on the subject." But he didn't push. It wasn't really his place. He and Simon weren't close or anything, and he wasn't a pushy guy. Most of the time. He could be sometimes. Like if there was a horse in his house.
If Simon wanted to talk, that was fine. If he didn't, that was fine too.
