Greg paused, and shook his head slightly, "Nah, I really shouldn't stay. I mean, I don't want you to feel pressured by me," he answred in a hoarse whiper, "Besides, I'm falling asleep, and it might be hard to explain...later...in the morning."
But he paused and starting to frown slightly, "If you know it is so cold, what were you doing up?" and he thought to press the issue but stopped. He wasn't sure he understood why Theo was out to begin with but Greg felt better, having looked after him.
