not the right glasses
true story
one day as my mother was half way down the stairs she asked me to get her glasses, so i went to the place she keeps them and showed them to her, she said they are not the right ones, so i went back and got her the other ones, she still said they were not the right ones, so i went back and got her and showed the previous glasses, and she said those are the ones, and i told her they were the ones i showed her before, she answered "i couldn't tell, i didn't have my glasses on.
