Certain translations are not perfect in Portuguese.
When user says: Boa noite (good night) the bot replies Opa! (someting like hey!)
the thing is that somethimes the person says Good Night/good day as a form of end of conversation. The best practice for the bot to reply is, in my opinon: Good night (to you too).
Is it possible for me to change it from OPA! to GOOD NIGHT! ?
