To me there is no sweeter sound, then to sit in the next room and hear my 4 & 2 year olds conversing and laughing. The things they say, and the way they communicate is absolutely an experience that everyone should be able to witness at least once in their lifetime. Sometimes I think its the only time they get along..."when no one's watching" :o) SO to two best friends who don't even know it "Thanks"
