From your individual perspective, the pronoun “I” belongs to you. The person in front of you is “other”.
Have you ever considered that you are the only person in the world who agrees with your appropriation of the pronoun “I”? For everyone else, you are not “I”. You are “other”.
“I” is a perspective; not a reality. Just as “here” only exists in reference to “there”, the pronoun “I” is just a point of view.
