A classmate and I recently discussed the difference between identical twins (monozygotic) and fraternal twins. Below, is a picture of my monozygotic twin and I when we were kids and also adults. There are differences, but a lot of similarities. :)

I believe I am the one on the left, but the jury is still out on that, since mom forgot to put the names on the back of the picture.

Now that we are older, I KNOW that I am on the left. LOL. My sister is tanner in this picture than me, and our personalities are pretty different. However, we still have the same mannerisms, voices and some aspects of our personalities. Therefore, people still get us mixed up.
