Dunno whether you guys have heard of Harmony.com. who promise "deep compatibility" based on your best match lol.
Every time the ad comes up on TV we laugh at the fact that if our details were fed into the database the memo would say "keep these people far apart!" Sometimes when we have a disagreement or different preference we tell each other "too bad we didn't fill in the form".
Example. In the early days we were making up the bed and he was tugging the sheet (which was too short) to cover the mattress down the bottom while I was tugging in the opposite direction. I said "I can't stand my head touching the mattress". Too bad, he informed me - he couldn't stand having his feet touch the mattress. I love being out in countryside - he thinks it's depressing without signs of civilisation. We've more or less carried on this way ever since exploring ever varied dimensions of our deeply incompatible views. Just as well we both think it's funny -
most of the time. see, that IS true, I wouldn't want to be with someone just like me...it's the differences that balance a relationship.
I don't think you can depend on a computer program to tell you if you are a match, there is so much more to love than a checklist..
