My mother used to sneak up to my door at night (at least she tried to, but I heard her most of the times), when I was supposed to be asleep, to look through the keyhole if there was light and listen if there were turned pages. I used to read at night with my fingers on the light switch (I had a lamp directly beside my bed), so I could turn it off without noise as soon as I heard her moving. Her bed was creaking no matter how careful she tried to get up and the floor was creaking too.
My father was another matter. He didn't even try to be quiet. He was fast. I knew, my mother wouldn't come in, if she didn't see light or hear me, but my father would be there with a few fast steps and open the door at once. I was just lucky that he mostly didn't care, if I was asleep or not. In his opinion it was my own fault, if I was tired the next day. And he was right. LOL. I often suffered the consequences of my late reading.
I always have a book with me, when I go somewhere where there might be waiting involved. I read while cooking, I even read while playing some stupid games on my cell phone. I read while I'm having breakfast and if I was alone I would read during the other meals, too. I read in bed, in busses and trains, on the toilet (lol),...
At every opportunity.
