When navigating in cars I often tell the driver to turn left when I mean right or v-v - most of my friends have cottoned on to this and double check with me before committing. After giving passing motorists directions to a pub or whatnot I often wonder whether I've sent them the wrong way!
I'm left handed - relevent to the problem?
Not a problem in my very limited flying experience - drive 152s/172s quite happily from right hand seat with right hand on yoke (just like driving a car in the UK really); more of a problem in gliders where I tended to prefer poling the stick left handed, prompting a "what are you going to use to operate the spoilers then?" from the instructor.
