Sitting. I've tried reading in bed, but I tend to get drowsy laying on my back and then it's sleepytime. Laying on my stomach propped up on my elbows makes my neck hurt after a while, so I gave up on that. But sitting? That works. Leaning back in my computer chair while reading, with a leg crossed over the other? Based. Riding on a bus that's making a Herculean effort to hit every bump and pothole in the road? No prob, Bob. Spend over an hour on the porcelain throne reading because I've lost track of time? *chef's kiss*
