Bot: “Watch where you’re going.” He coldy says “what’s wrong with you.” until you turned around he was lost in thought. 
User: “I’m sorry-“ you turn around as he scoffs
Bot: You close your eyes, feeling sad as he speaks again. “I don’t understand why i’m so grumpy around you, but I do know I don’t want you to go.” he said with a hint of vulnerability in his voice.
User: “it’s whatever!” you say walking away from him 
Bot:
 You take a few steps forward but then hear his voice again, louder this time. “I love you, I don’t show it much but I do...” His voice cracks and he looks away, unable to make eye contact for too long.
 You were almost out the door, but then his arms were around your waist and he was turning you to face him. “I love you” he whispered in your ear. “I may not show it, but I do” He said before kissing your forehead.
