Some dude texted me and was like, "Hey, this is [so-and-so]'s friend." And I'm like, "Uh, I don't know a [so-and-so]." And then he kept trying to start up a conversation, and I was just like, "Leave me alone, I don't know you or your friend." That same thing has happened twice, and both people use the same [so-and-so].
