That may be surprising people.
Living in Czech, my problem is that it’s still hard for me to distinguish most local people from appearance. For detail, I might be able to do it. But I am not confident for that.
Of course each people has a different personality, energy. The facial expressions and the posture describe those. I can distinguish about those.
Anyway. After talking in person, I can believe that I am really talking with the person that I think.
This may be a common experience of foreigner from Asia. Or it may be my missing point. And instead I may be able to distinguish another thing.
Because an amount of time people can use in a day is same, and an amount of the information people can deal with in a day may be likely to being same.
