It's not a sick idea, it's a logical idea, and a great one. But there are only two problems with it:

1) Assuming we have the typical moral standards regarding marriage, once you've made that committment it's too late. You only get one chance in life, and if you realize later you've made the wrong choice, sorry, but you're SOL, game over, no second chance.

2) The logical flaw of assuming the guests at the party would play by the rules and be honest in their selection of nametags. I would be willing to bet that a good number of the LD spouses that those of us here wound up with after marriage were all but downright flamboyantly "strutting HD badges" before marriage, if you know what I mean. After all, if they had been honest about their true LD status, we wouldn't have married them, and we wouldn't be in this mess now, and that's what makes a maddening situation even more maddening. The knowledge that we got gyped through dishonesty.
