This is a quote from a beautiful little book by D. Knuth called Surreal Numbers.
B: I wonder why this mathematics is so exciting now, when it was so dull in school. Do you remember old Professor Landau's lectures? I used to really hate that class: Theorem, proof, lemma, remark, theorem, proof, what a total drag.
A: Yes, I remember having a tough time staying awake. But look, wouldn't our beautiful discoveries be just about the same?
B: True. I've got this mad urge to get up before a class and present our results: Theorem, proof, lemma, remark. I'd make it so slick, nobody would be able to guess how we did it, and everyone would be so impressed.
A: Or bored.
B: Yes, there's that. I guess the excitement and the beauty comes in the discovery, not the hearing.
A: But it is beautiful. And I enjoyed hearing your discoveries at most as much as making my own. So what's the real difference?
B: I guess you're right at that. I was able to really appreciate what you did, because I had already been struggling with the same problem myself.
... and so on.
