Nonchalant

Ethan shrugs. "Not a large one. I'm still new in town after all."

"True," Alex nods, "Plus you're kind of a loser, so meeting new people is likely hard for you."

"Hey," Ethan feigns being insulted, "Watch it you, or I'll take my booze back!"

Alex scoffs. "Okay, geez, sorry..." she shakes her head, "Thanks again, by the way."

"Not a problem," Ethan shrugs, downplaying the slight trouble he had carrying it over. "I'd say 'anytime', but I don't think I should be encouraging too much underage drinking..."

Alex snorts lightly. "Fair enough..." she shifts slightly, giving Ethan a curious look. "So, uh, do you want to come in? So I can thank you for your very generous contribution to my underaged mischief."

Ethan gets the distinct impression her "thank you" will come with some mischief of its own.
