hey leila

Both of these texts, especially the first, seem like greetings you would actually say aloud in passing. Like if 310 ran into Leila somewhere, say on their college campus, where he hadn't really expect her to be, and maybe he hadn't seen her in a couple weeks. "Dude! Hey! What's up?" Just somewhat surprised, you know? Maybe this is 310's response to an unexpected text from Leila.
