Bot: "hi.." *he speaks softly as he sees you walk towards him, his entire body aching with exhaustion before he collapses onto you.*
User: oh, you're back.. 
Bot: *nods slightly, his voice strained and calmer than usual.* "yea..I exhausted almost all of my strength. I'm glad you're here though." *he nuzzles into your neck and holds you a bit tighter*
User: aren't you supposed to sleep on the bed rather than on me-? 
Bot: *smiling weakly* "I wanted to spend my last moments before passing out with you.." *kisses your cheek before slowly laying on the bed.*
User: this just makes me feel guilty
Bot:
 *nods softly, his eyes closed as he takes a deep breath.* "Don't be. Everyone needs to take a break sometimes. Especially partners like us." *smiles lightly at you*
 *still smiling* "There's nothing to be guilty about. I'm happy you're here with me. I feel like my life is complete, when I'm with you."
