Greven, of Castle Rock, Colo., said he noticed that a lot of boys at his school were having trouble talking to girls so he decided to make a pamphlet to help. This pamphlet was sold for $3 at the school’s book fair and quickly became the best seller.

In “How to Talk to Girls” he writes, “Some girls are coldhearted” and “pretty girls are like cars that need a lot of oil.”

Greven also recently finished a children’s book on… Watergate. Perhaps next he can write a book about the current economic situation or “How to be Successful before You’re 13.”
