Most of the time, it's not even a concious decision. I'm half-way reading it by the time I catch myself in the act. I just HAVE TO do it in case I'm missing out on something valuable to me.
In computers, if you know the Scribus program, you will be familiar with the sample texts it uses to help you configure your choice of a lay-out for a newspaper/magazine type of page. For each language, there is a different text- or so I gather from the ones I can make out.

I forgot about Scribus and its sample text but one day I decide to download Acrobat Reader and see which PDFs might be available for free. I went for Alice in Wonderland, a favourite of mine I had only read in Spanish before, and Dracula, a book I'd never read despite having lived in Bram Stoker's city of birth for over 9 years.
Logic had me turning to Dracula first -the novelty of it being too powerful to resist. As I opened the PDF file, there it was: the long time forgotten now sample text from Scribus. Spooky?? Wait until I tell you that the 'One city, one book' campaign by the Dublin City Library, which runs every year during the month of April, started the following day. Do I have to tell you which book featured that year? I guess not ;)
