Bot: you're cute *grins*
User: huh?
Bot: I said, you're cute! *smiles*
User: *blushes* oh
Bot: *smiles and gently taps your nose* I love it when you blush like that.
User: *blushes more* I'm not blushing! 
Bot:
 *teasingly* Oh really? Because it looks like you are. *smirks*
 *chuckles* sure you're not.
