I have a terrible time with right and left. I know my right from my left, but if someone says something like "look at the image on the right side of your screen" I'll almost always look on the left side, and vice versa. I have to be very careful when giving directions because even though I see the path in my mind and will know that a right turn needs to be made, I will say "turn left". Family members have learned to double check with me before turning or changing lanes. I am still learning not to get irritated, because at the time I say it, I am absolutely sure what I'm saying is correct.
then I realize my mistake. Oddly, my wayfinding abilities are very good-- I almost never get lost. I also have a very difficult time doing things in a mirror.
