Why do I call myself Tyra?

Well, I don't why the name survived my whole live, but here is the short story:

Many years ago on my birthday I got a 'Erstes Sachbuch für Kinder' book from my grandmother. You can find everything in there: the story from the first moon landing, the reproduction of flowers and of course something about saurians.
There were some pictures of different saurians in that chapter but I was just interested in one: it showed a Tyrannosaurian - I fell in love from the first sight...

From that time on I called everything 'Tyra' that had something to do with me: I had one a CB-sender. Of course my name was 'Tyra'. Guess how I named my floppydisks on my first C-64. I'm still not better: all my harddisks and floppies have 'Tyra' in there name.

So you can imagine that it was just a must that my username for every internet account has to be 'Tyra'.

BTW: if you can see this nice little saurian on the top of the table of contents to the left: this is the tyra that gave me the name...
