@Fizbosshoes Yes! Like your presence means their brain is totally redundant, default to your brain!
My sister does this too but.. then argues with what I say. So she will ask me what exit off a roundabout, I'll tell her, then she will say 'this one' just as its almost too late, which makes me hesitate because surely I just said that one so why is she questioning it.. so she sails past and then blames ME...
At all major junctions I now inform her 'I have shut my eyes, I cannot offer an opinion' and refuse to speak until we're past.
She is perfectly capable of navigating her ass round the country by herself and does, FOR WORK on a daily basis.
DP does the 'not looking' thing, for him an item is 'lost' if on turning 360 around the room with eyes open, he cannot immediately see it/it does not leap into his hands. Do that in all rooms in the house, item does not appear, item is now LOST FOREVER, DRAMA AND DOOM.
Then theres some back and forth about actually looking meaning more than standing about eyes open hoping for the item to walk up and prod him.. and then I look or make him look somewhere I can't reach and lo... the item is discovered, usually right where I said it'd be!
