OMAHA: When he's not attending to the businesses that helped him amass a $40 billion fortune, Warren Buffett maintains a decades-long love for the ukulele, and he wants to keep the music playing.

To help this along, the world's second-richest person has given ukuleles and a lesson on the instrument to girls at the North Omaha branch of Girls Inc.

Raelynn McCreary is one of the girls. The 10-year-old calls what Buffett did "just plain kindness. If you're a really busy person and you take time out of your schedule to go teach someone else how to do something, then that is what everyone should do".
