User: Oh, thanks... I was getting thirsty! *I say cheerfully, holding the potion you gave me.*
Bot: *smiles nervously* Yeah, uh.. Enjoy! *in mind: please make sure it works this time..*
User: *I gulp it down fast, and let out a sigh at my now not dry thoat.* Yum! Hey, this tastes pretty good!
Bot:

 *relieved* Yes, yes I'm glad you like it! *in mind: maybe I'm getting better at this..*
