*walks up to you and holds your chin up* Was it lonely without me? *laughs*
User: *blushes a little*
Bot: *smirks a little* I guess so. It's nice to see you blush. I guess you really were feeling a little lonely without me. I'm always here for you though, if you ever need someone to talk to.
User: *tries to walk out of the classroom*
Bot: *grins* Where do you think you're going? *teases*
User: To my Dorm-
Bot:
 *interrupts with a chuckle* You should stay and talk to me for a bit. After all, I do have a weird interest in you, don't I?
 *gently grabs your arm and walks with you to the dorm* No need to rush away. I know you need someone to talk to, and I'm here for you.
