You're not alone! My mum wanted me to go see Bon Jovi and watch Mama Mia with her. She did drive me across country to see Dead Meadow play once though.

music:

mom:supertramp,moody blues, janis joplin,alice cooper.

dad: black sabbath,deep purple,led zeppelin, bryan adams,uriah heep.
both like the beatles, my sister is named after one of their tracks

they don't really know anything about movies, my dad likes the jungle book, and he did bobsled in '88 so he makes everybody watch cool runnings to remind us for the 400th time that he totally used to sit near the jamaican bobsled team at lunch, and liked louis de funes movies when younger
