Honesty is the Rules Girl Policy
If we don't like you, we're not going to pretend that we do.
(we might not be 100% sold on the idea, but we won't mess with you...)
If we don't want to date you anymore, we'll tell you why (nicely/tactfully, but truthfully).
If we don't want to see that movie but we know you really want to (we'll go, but we don't have to love it or do this for you every weekend)
If we are craving Cafe Rio and you want Wendy's (both excellent choices by the way), we're going to tell you and we'll talk it out.
Rules Girls have a very strict honesty policy because we are always true to who we are. We aren't very good "people pleasers" because that's clearly unhealthy.
