So most of you probably don't know this. I am face blind. Its not like everyone walks around without a face, but I lack the ability to snap recognize human faces the same way humans lack the ability to snap recognize an animals face. You can tell them apart with a little study but thats it.

So am I! I have moderate prosopagnosia. Most people look similar. They need unique haircuts or hair colours for me to recognize them. Or facial hair. (Sometimes I go by gait.)
