You're right, I'm an Aquarius, and I am nicer to strangers than my own friends, but I don't see it as being mean or nice. I'm more honest with my friends, because I thought we're supposed to have an honest, transparent, supportive relationship, and we're supposed to tell our friends the truth about ourselves. Maybe some people like to keep secrets, you know? I like to be productive, and I like my friends to be honest with me about my issues, too.
