Martha does smile then; a smile that basically says Thanks for being gallant. Because she can't believe she didn't come off as crazy. But the smile turns more real after a second as she nods.
"See you around. Drinks and normalcy next time sound good?" she asks as she backs away. She laughs to signal it was half rhetorical, but waits just a beat longer to see if there's a reply before walking away in earnest.
[OOC: Just in case you do want to follow up, Martha will be attending this. She says she's more of a listener, but she might talk too...]
