It's really great when after a first date, both parties tacitly agree to never see each other again. This is the best possible option - oh wait, yeah, it would be better if they actually like each other. Scratch that.
But this outcome is way better and less messy than something one-sided. How simple and wonderful to say goodbye, mutually thinking, "Well this was fun, we both merely tolerated one another, but hey, we gave it a shot. The end."
Done and done!
