The thing is......how are you being a good friend if you won't help her see how erroneous her behaviour actually is? Your refusal to see it notwithstanding, I believe there was at least a half dozen people here that told you as much - what does that tell you? With the weight of opinion behind the argument that anyone who'd do that is, well, a bitch? It's one thing for her to complain - completely another for you to pop a breath mint to placate her whim - it's a completely inexcusable thing for her not to go, "Hey don't worry about doing that" upon discovering what you were doing to please her. Which equals a totally, utterly, completely self obsessed, self centered, unempathetic B-I-T-C-H.
Have you ever drank orange juice after brushing your teeth? That's somewhat akin to how beer would taste after breath mints. Why would you do that to yourself?
YES. Oh god yes. Fuckin shit man...I used to be in such a rush for work I'd brush and just spit and be out the door without the rinse so it certainly didn't help either...Fruit Punch was no better.
