The worst thing I could come up with, is not that difficult, but it is bothersome.
I often have trouble with my right and lefts so I have to come up with a mnemonic to remember correctly. For example, to remember what side of the plate the knife versus fork goes on, I have to think “fork has four letters, left has four letters, the fork goes on the left side. The knife has five letters like right, so it goes on the right side.”
I also help remind myself by making an L with both the right and left hands….Fortunately, my sense of direction is amazing. On instinct, I know where to go, instead of worrying about my rights and lefts.
I may have mild dyslexia because I occasionally write my b’s as p’s but it doesn’t slow me down while reading!
