Birth-order theory

States that the older child should be systematically different to later children.
On average, they should generally be more conservative, more disciplinarian and more conservative. And, ultimately, more independent.
This is because, amongst other things the parents will probably pay more attention to the first child, being parents for the first time. They will spend more time trying to make the baby "perfect" than their next. They will be more disciplinarian and less lax generally, and will likely make more mistakes, being novices.
Obviously this might apply in a different way - the opposite could be true in some cases.
The point is though that parenting attitudes change over time, and they try to learn from their mistakes, with a probable affect on the children's personalities. Does this apply to anyone out there?

Collecting

This is a confessional. One of my strange psychological quirks is my desire to archive things. It's crazy, self-centred, and it consumes an hour every few weeks or so. I've just always hated the feeling of losing my memories. It's a fantastic feeling when you're able to see your past before you, when you wish to. To know that while your memory may one day fail, you will not forget. I'll appreciate it in my old age. (Although I'm working on keeping the past in its context and not letting it interfere with the present).

I've got collections of travel diaries from every holiday since I was 7 (Those are funny to read, I wrote the precise time we arrived at places more than what we saw). From my travels, I also have old passes to mountain ranges, tickets from trains, museums, trams, productions I attended, films, art galleries, clubs. If I enjoyed overseas music, it has been downloaded and forms the audio part of my travel memories folders, nearby the photos.
I've got all my writings for the last 5 years and many from before, with the date of writing mentioned, and the content categorised. I've got archives of every conversation I've ever had on MSN, archives of interesting web pages or articles I've saved to my hard disk for retrieval when my interest on researching a subject is reignited. Old mIRC programming, and other nerdy material.
I'll have almost all my photos right back to primary school camps, and even my dad's old 35mm slides digitized and filed away on my computer in their appropriate place.
I've got diaries, dream diaries, dead end writings, old workbooks. Lists of my top 50, 100 books, movies. I've got stand-up comedies, film clips, TV shows. Data systems with application backups. On an external hard drive I've also got just about every computer game I ever played (I no longer play them). I've got old clothes, old trophies, team memorabilia, board games.

It's compulsive, addictive, but it's incredibly satisfying for me and it's proven very useful many times. I thought I was going to run out physical space, but most things are digital now anyway. Even this blog is sort of an archive. I wonder how long I'll keep everything up for.
