Why should I get upset if someone doesn't have the same taste in books and movies as me? No one has the same taste in everything.
I like my steaks rare. My mom likes her well-done.
I like sushi. My mom hates fish.
I like venison. My mom won't eat game.
I love mushrooms. My dad hates them.
My sister loves kiwi fruit. I think it's nasty.
My sister listens to Olivia Newton-John, has since the 70's. I don't, never did, never will.
I like classic rock hair bands, my sister hates them.
I like fried jalapenoes. One of my best friends hates spicy food.
I like action and espionage movies, my sister likes rom-coms and slapstick.
And none of us think less of the other because of it.
