One of the suggestions for taking lomos is 'shoot from the hip'. This picture was taken like that, at hip level so that the subjects wouldn't know they were being photographed. This involves seeing a composition, quickly adjusting the focus, then guessing the shooting angle as you nonchalently stroll past, looking anywhere but at the subject. Unsurprisingly, you rarely get the result you're aiming for, but in this case it worked reasonably well.
