Yes! I hate when a guy I've already told that I'm married keeps asking me out. It's rude and the answer is still no. I have to have this convo all the time. It's ridiculous and usually the same dudes every time. I've stopped being polite about it.
I think the almost infinite freedom this truth represents is overwhelming to many people. Thus, their adherence to the lines. I think people who understand and enjoy this freedom are happier. But the others cannot be pushed. It must always be a choice.
