One time was discussing with friend that was convinced that you could simply explain things to kids. He was thinking it was odd that if someone gets pissed off about questions, when you can simply explain it. I mentioned that its possible you haven't really had such talk, and it's roughly 3-5 questions, further when you really can't explain, since whatever questions are being asked, one just have to decide level where somethings is given, so to say.
One could easily explain things they like in noise, but it is very close to almost any human desire, that it is irrational emotion where you do not have real explanation. Like explaining why you have specific taste? One usually can describe some sort of qualities that you like and prefer over something else, but does this taste itself have "explanation"? Most likely not and probably is something irrational, beyond the simple cultural or biological explanation.
Few decades ago, when I was teenager living with parents, some folks came to visit and they had same age teenage girl with them and we hang out in my room and girl mentions that she is little strange, that she likes music like Toto. I asked is she'd like to hear something weird, and pulled out Bizarre Uproar/Man Is The Bastard -split 7", put that on stereos. She sat through entire side of 7" and then said "I'll go check out what my parents are doing".
