Do you find yourself defending them a lot? Are your tastes for music, food, movies, humor, etc. more acquired, or more intrinsic? Do you tend to indulge your preferences based on what you can afford? Is your motive for trying something new primarily curiosity, suggestion, trust or resourcefulness? Or maybe to confirm your worst judgement on the matter? The pics I've posted are examples of my own taste-cravings fulfilled at one point or another. I left out music cause y'all tend to freak out on that subject ;). Plus, I'm lazy.
Most of my tastes I acquired from my Dad. My brother & I both like classical music, the Stones & the Beatles because of him. My taste in books has a lot to do with him, and with life after college. With food, I'll try just about anything out of curiosity. My older friend, whom I admired, stepped out once when I was eighteen. I looked at her bookshelf and snuck a peek in her fridge because I wanted to see what a woman like her ingested to make her so fabulous. This is where I discovered the "acquired taste".
I'd tried an olive, which I hate. Once every five years I see if I still hate them. Her place is where I quickly picked up on salt & vinegar potato chips, black coffee, etc.
My taste in books is pretty linear. First off, I'll read just about any genre pertinent to my own current preoccupation- humor, politics, biography, fiction, horror. I have to REALLY trust someone's experience before I read a book suggested to me... I've had too many weird experiences of a friend & me making pained faces at each other because the book meant SO MUCH to them, and I couldn't for the life of me get into it. And visa-versa.
