I recognise faces, but have difficulty remembering the name that should go with each particular face.
As I teacher, I asked my classes to please sit in the same places for at least the first month of term and drew a plan of the classroom with their names written in, so I had a chance of learning to associate the right name and face.
Once digital cameras came on the scene life became much easier - none of my pupils, or their parents, objected to my taking a photo that was only ever printed onto my classroom plan and then deleted from my laptop.
But I know every cat in the neighbourhood and approximately where it lives and and know which child lives where.
I also notice squirrels, hares and other wild animals, plants and trees.
I am also good at noticing when friends are happy or sad.
Most of us are observant about the things that really interest us.
