Just one hour a week.

That's how little time it takes to make a difference in someone's life.

You can be a mentor to a little boy or girl through Big Brothers, Big Sisters of Central Arkansas, just like Nathan and Nicolas.

The two enjoy lots of activities together including basketball, building blocks and playing on the computer.

Nicolas says he decided to be a big brother because of his big brother -- who gave him lots of advice and guidance.

Here's what Nathan said when we asked him why he liked having a big brother.

"I like when i talk he listens and when he talks i listen and he isn't like one of those selfish people that are always like me, me, me."
