I didn't know anyone had any standard until a conversation on here where it came up a year or two ago. Every place I've lived had two switches somewhere (both ends of a hallway, both entrances to a room, etc) so I never internalized any directionality for switches - it's just always been "flip the switch if the light is in the wrong state". One or two of the switches I've had have even been sideways.
