My two oldest boys are Irish twins, less than a year apart. There wasn't much that they weren't competitive about. The real challenges came as they developed friendships with others in their pre-teen and teen years, and they were very competitive about who hung out with who and who was doing what. And again, it's important as a parent to listen to each. When they're having a brawl, they each have a side. You have to take them aside, break them apart and find out what's your problem, Tim, what's your problem, Matt. Let them say what they want to say. They talk about a speech that I gave them years ago that I forgot. They call it "the annual speech". I went and got my high school manual, and I came in and I opened it up. I showed them my four best friends and what they had written about me, then I ask them, "Do you know these guys?" And they knew one of them, they'd heard of another one, they didn't know the other two. And my point to them was that you two are going to spend every important day that lies in the future, be it a wedding, a baptism, a funeral, a holiday; you will always be bound by the fact that you're brother and brother. And look at these friends that you're fighting over. They seem like the most important thing in the world today, but here I am years later. I have fond memories of those folks, but I don't see them anymore, but I still see my brother and sisters.
