Sorry about the delay!
Martha was definitely the friendly type. It came across as flirtatious is some ways, but she didn't mind. She wasn't about to change who or how she was to make someone else comfortable. Mack seemed at ease, though, and she took that as a green light to stick around and chat him up a bit.
She surveyed the roof carefully, and moved around from one side to the other to examine it from all angles. She made a soft "hmmm" sound as she thought, and when she was satisfied with her assessment she turned to Mack. "Well, to be honest, I think that maybe you could use a few of the thicker palm leaves on the top. To help weight it down." Her brow was furrowed slightly as she looked at him, waiting to see if maybe he agreed with what she was saying.
"I mean, it's already pretty well-built right now," she almost stammered. "But if you think that roof is missing something I think it might be that."
