Olive Theory

According to my new favourite tv show, "how i met your mother", there is a cute theory called "Olive Theory".

The theory says that if someone who loves olives meets someone who hates olives, they will make a great couple. (or using the show's term, "awesome couple") Because one will compliment the other well.

I understand that theory, however, what if someone who loves olives meets another person who also loves olives? Do they share? What if one of them loves olives more than the other? Do they compromise? Do they fight? Does one of them eat all of the olives and make the other to get more olives?

How about 2 people who hate olives get together? Does one of them force the other to pick all the olives?

I think it is harder to find someone to compliment you than to compromise for the things you dont like.
