Inna row....
Fire:
Well...the fire I think you're talking about is probably the "process of combustion of inflammable materials producing heat and light and (often) smoke" (as defined by wordnet, princeton)...and thus is a process, and thus takes up no space as it is neither matter nor energy, but a process which involves the two. However, if you are calling a stack of wood that happens to be burning a "fire", then the "fire" takes up just as much space as all that wood, and the smoke being produced.
High School:
The school I went to...was not full of stereotypes, but had some; and as far as I could tell had no racial wars going on either. Really, the two "stereotypes" that I've seen in my high school are basically the 10% of students doing nearly everything--from acting in plays to taking AP math courses--and the 90% or so who...don't. (Percentages are not necessarily accurate, but the former group is definitely a minority).
Life a Dream:
Well, DUH! We probably all wonder that at some point or other--where do you think they got the line "life is but a dream" from? ...And the only reason this is less nice and scholarly than my other answers is because you had to stab me. Bleh.
Humor:
Humor is really hard to properly define. I mean, we could say that society defines humor, but even babies laugh. So...I guess it's some kind of instinct, where certain things strike a person as being funny, and it's eventually informed by the conscious mind and knowledge, which is why some people find different things funny.
But I have to say I kinda disagree with Asmo's theory a little bit. I mean, as far as saying "humor is the unexpected" and "the unexpected is humor", I don't think either statement is necessarily true. They aren't entirely false either, though...Some surprises are just not funny, but then again one might say "I laugh about this now, but at the time it really sucked"...
Dating:
I dunno. I've never actually dated, so...yeah.
Amsterdam:
Never been there..sorry. Pass.
And a question from me...
What does money actually mean? I mean, sure, we have a paper bill (or a coin, whatever). And we're told that bill represents gold. But gold is not, in and of itself, useful. Its only value is the value that people place on it, and I guess a few industrial values. But tin and iron, for instance, have at least as many uses, and are not valued as highly. So...why do we trade money at all, when it has no worth? Or if it DOES have an intrinsic worth, what is it?
