They say you are not you except in terms of relation to other people. If there weren't any other people there wouldn't be any you because what you do, which is what you are, only has meaning in relation to other people.
Nothing can be by itself alone, no one can be by himself or herself alone, everyone has to inter-be with every one else. That is why, when you look outside, around you, you can see yourself.

Maybe I’m a human, but I’m a me-and-Ma as well.

The isolated individual is not a real person. A real person is one who lives in and for others.
