>>6 I guess that's unavoidable.
Let's put it this way: let's imagine that each person is a polyhedron, and each of its faces is one facet of who they are as a person. Some people are pyramids, some people are cubes, and some are fucking icosahedrons; but everyone has at least some depth to them.
Now, the way I see it, you could never really expect to see all of another person's faces at the same time. At best, if you get real close, you can see clearly like half of the faces, and maybe some others kind of smudged by the shade. Most of the time you'll just see one of the polyhedron's faces (maybe even two if you happen to glance from a corner) like if it was a paper-thin, vaguely misshapen polygon, and you'll either assume there's no further depth or not care enough to get closer and find it. And then, of course, there are people that aren't even looking and say that your polyhedron is actually a potato, because they know a potato when they see one, and how dare you be a potato and not a polyhedron like everyone else.
But even then, I don't think anyone can accurately see all of their own faces. Going back to the analogy because I'm already knee-high in it, seeing your own polyhedron from the inside kind lets you see all of your faces at the same time, but since you're looking from a different perspective, you get a different kind of distortion than anyone looking from the outside. Sometimes you're a bit blind to some of your bad traits, and some times you're a bit blind to some of your good ones, but there will always be at least a couple of faces that you'll see as blurry and kind of misshapen.
TL;DR: Everyone is complicated and figuring out other people (and even yourself) is hard. There will always be some discrepancy between the "you" other people see and the "you" you see, and probably the real one is some sort of combination between the two.
Corollary: If you feel like the people that are close to you aren't seeing some sides of you that you find important, let them know how you feel. Opening up can be scary, but it usually pays off.
