are you a younger clone of them or are your world views totally different? what do you agree and disagree on?
differences - politics cos I live with a bunch of rabidly partisan Tories who never shut up about how Gordon Brown sold all the gold #prayforme, sport because I think cricket is absolute balls but my brother is obsessed with it so my parents are interested too, religion - my mum works at a church and goes to Bible Study groups, I am an atheist. with stuff like equality/'political correctness', I tend to hugely disagree with dad/brother (who both think I deliberately argue with them for fun and love to accuse me of being on a soapbox :/ ) but my mum's a lot more open minded.
similarities - similar travel views to my mum (go and explore where you're going on holiday! go to new places! SEE THE WORLD!), similar taste in TV to parents (except comedy), tend to agree with my dad on all things Tonbridge Angels.
now you go.
