Dexter never knew what to do with crying. He didn't know how to comfort people and always felt really awkward when he tried. Of all the things he tried to emulate, this was the thing he had the most trouble with.
"Don't... just..." Dexter cleared his throat. "I don't even know if these are honest tears, or just the way you manipulate other people. I can't tell. I have no idea."
The fact that he was speaking with somebody who would use a tactic like that made him feel like he should be walking out right now and not engaging her further. Females like that were nothing but trouble.
