Sheldon... Cooper? "An ex of yours?" If so, he wasn't flattered by the comparison. "I don't flail. Much." Bite of sandwich, meet mouth. He sort of liked her hugs. It was something he wasn't used to at first, as cars didn't seem to get many hugs, but he was becoming accustomed to her invasion of his personal space. Even coming to anticipate it.

Best to have some of these things sorted out in the early days, most definitely. He could face her again.
