Goth Girl

Ok ... I don't have a clue what Goths and such like is all about. I really don't. It all goes way over my head. I'm not a fan. It turns pretty young girls into freaks, and guys just look plain daft. In saying that, this image obviously caught my eye. What is it all about though? It's obviously a young girls school bag/rucksack, but shaped as a coffin? And why the tartan? Scottish Dracula????

I'm lost .... come on Goths, freaks, whatever you are ..... educate me on this one! :-)
