He was vaguely aware of the splinters, but his fingers were so callused, he knew he was relatively safe. The point was to avoid infection as much as possible. "It does," he replied, nodding. "It is always better to hope than to assume the worst. After centuries of assuming the worst, I've only just begun to learn that hope is better."

"I don't foresee much building as being necessary - only viable shelters in the event of rain, which is possible given the climate. As for the bitch of this situation, I'm more inclined to say prolonged sun exposure is going to be difficult. Still, sparring may do to take our minds off of this."
Looking up, he shook his head and held up a thicker piece of wood. One acceptable for a fire. "No, not often. But sometimes...there is reason for it."
