i doubt you truly have a problem, probably just some minor short term memory loss. you could also have prosopagnosia, otherwise known as being “face blind”. when you are face blind, you have no problem remembering important events, facts, and so on, but your brain just can’t seem to recognize the faces if you try to think about them. but don’t worry, a lot of people have this condition, it’s really minute, nothing to worry about. there are more important things in life than physical appearance anyway. i guess you’ll just have to make sure that if you watch a new movie or show, you’re always accompanied by someone without “face blindness.”
