ANNIKA and KERSTIN recently spent time between DEBATE TOURNAMENT rounds quizzing each other with homemade FLASH CARDS about bands they enjoy.
Two observations immediately sprang to my mind.

I never really thought they were listening to my musical obsessive's ramblings during their impressionable years.
