Terran teens and children often go through phases while they're growing up, such as anime, emo, rebellious, etc (and some people stay like that forever and we especially love those people.)
Did your kids have any phases growing up?
Sybock listened exclusively to 20th century Terran rock and metal music for five-point-four months when he was 17 standard years of age. I believe his preferred musicians were Guns and Roses, Metallica, AC/DC, and Black Sabbath, to name a few.
For three-point-eight years of his life, Spock took a great interest in Vulcan's selection of natural geodes and rock formations. He amassed a large collection, some of which is now housed in storage or donated to off-planet xenogeological research centers, and refused to participate in many activities that did not include, in some fashion, his fondness for rocks. I believe he was 7 standard years of age when this phase began.
