Some may say this is a microcosm of what is occurring on a societal level.

Unfortunately, much of society's response to date has been to cut down tall poppies. A better response is needed and would be beneficial to all, from the most gifted individual striving to develop her gifts, to the bully who learns to accept that she is a unique individual with her own strengths, talents, and challenges... different not "less than".

Please continue to encourage your daughter to always be/do her best! Understanding and maintaining healthy personal boundaries may be key.
