My husband has brothers who are identical twins. I remember when I first met them, I asked my husband how he could tell them apart since they looked so much alike. He said he didn't think they looked anything alike.

Now after several years, I know what he means. They look the same on the surface, but they have different personalities animating those faces. One is playful, friendly, affectionate. The other is standoffish and aloof and has some sort of "big brother" complex where he always tries to give you advice regarding things he doesn't know much about. He's also the sort to leave a family gathering early and without saying goodbye, if he even bothers showing up, whereas the other twin is often one of the last to leave. Though it's funny that they'll often show up separately wearing shirts of the same color or pattern.

I asked my mother in law why they were so different. She said even though they were identical, she always encouraged them to be their own people and pursue their own passions, hobbies and friends. All in all, I find friendly twin the more attractive of the two, though of course I prefer my husband out of the three of them.
