sleepless night reading

I couldn't sleep last night, so I naturally went online to kill time. I went on facebook and almost for the time time I found myself reading my friends' notes...over three pages of them. it was very interesting I have to say.
there was the usual comments on current affairs, political stuff, there were a couple of poems, there was actually no boring pieces like "I had two eggs and a sausage for breakfast, the tomato squirted into my friend's face when I stabbed it with my fork......". the most recurring theme, at least at the time of reading, is around telling the world about yourself. I found two categories, one is "answer these questions TRUTHFULLY", and the other is "25 random things about you that others might not know". I suppose what makes these nice to read is that they help make the connection between friends, you begin to realise that there is more in common between yourself and the friend. or, you learn more about your friend so that you have a much better profile of what he/she is like, which boils down to gaining a greater understanding of the friendship.
well I like reading philosophy or theoretical stuff, I very rarely read a fiction. I love knowing about development of ideas etc. but still, 3 o'clock in the morning there's just nothing better than reading what my friends are like! on top of that, surely profiling someone isn't really easy, deducing what their character is like from a few facts is just not simple yet I guess we all enjoy doing it, unlike deducing say facts from philosophical or mathematical theories which only a few of us like to do. I reccon that we are simply soooo good at profiling and understanding people that we manage to find so much satisfaction in processing it so that we don't mind doing that kind of tasks even 3 o'clock AM.
