I am fortunate to have two very young siblings, one is a 5yr lad, the other a 7yr old girl. I'm 29 and try to influence them growing up as much as possible (the parents can stuff it if they think they're going to turn out just like them
).
This means they are subjected to stuff I deem as "real good stuff"... like the following: Led Zeppelin, Deep Purple, Michael Jackson, Transformers, Labrinth (and thus David Bowie), Back to the Future and other such cult classic things that all people should have in their life and respect. Tonight it's the Goonies, and listening to them down the hallway I can hear them roaring with laughter - another generation hooked - RESULT!
When they're old enough it will be Billy Conolly amd Dawn of the Dead
What do you enforce upon your kids/little siblings?
