The girl packs are usually closely followed by swarms of leering teenage boys. Usually football player-types wearing shorts and their football jerseys, even in 90° heat. Lots of pressure for high school football players. I remember that pressure.
Then there are other packs of teenagers who I am told are called "Goths." They have dyed black hair, lots of facial piercings in some very unlikely places, very pale skin and black clothing. I think they believe in some stuff that I don't want to know about. Must be tough being a Goth. They have to get all those piercings, keep their hair dyed and sneak out of the house to avoid parents who may want to know about their secret Goth philosophy, which is probably way too complicated for me to understand and must involve a lot of study and meditation.
