person A: I lied to my friend about something and told her something was okay when it really wasn't
person B: Oh. I know lying is sometimes beneficial in some situations. Hopefully you did this to protect someone's feelings
person A: I just felt really bad and guilty that I did it.
person B: Yeah_comma_ I think that means you have a conscience_comma_ which is a good thing. If you didn't feel bad_comma_ I'd worry about you!
