Lying down is mine. I generally read for about an hour before going to sleep at night, mostly on the couch in the living room. If my Not-Wife is watching a particularly annoying reality TV show (ie, all of them), I'll often head up to the bedroom and have a good read. Quiet, you in the back. Quit your sniggering. I said good read.
Problem is, after a long day at the office, it's very easy to nod off, leaving me wide awake until about 1 or 2am. So sometimes I make a point of reading while seated, but it feels unnatural to me, having read lying down for most of my life.
Now you've all probably had an insight into my private life that you'd rather do without. If you're not in the corner, rocking, whimpering, and sucking on your thumb, I'd like to know ...
... what's your favourite position?
