Some paperbacks have pages use a grade of paper or something that make it easy to put your finger on either the top edge or bottom edge of a page and turn to the next one. Some, like the one I'm currently reading, do not, and about a quarter of the time I get two pages or even have to struggle not to get more. Because thinking about it or struggling to turn the page causes a discontinuity in world immersion, all of the time prepare to get to the next page at a good paragraph break partway down the right hand page, even if I am not going there immediately. Thank goodness for page numbering! :
Last night, though, I was trying to separate to get to the next page. It was clearly two pages since it felt too thick. After fighting it I double-checked the page numbers. Sure enough, it was just one page. Doh! That's a first for me.
In completely unrelated news I have now been unable to sleep for 48 hours. I do lie in bed with my eyes closed for the standard amount of time, which seems almost sufficient, but I haven't done over 30 since about '95 (my self-inflicted record was 60 as a teen, which was followed by a total collapse and 17 of deep sleep).
