Nobody knows what goes on inside your head
In turn, you don’t know what goes inside theirs.
We go through life guessing, assuming, and dictating what we think others are thinking. Little do we know how wrong or maybe right we are.
How can we know someone, better than we know ourselves? We could know someone, but maybe they changed or perhaps you were only seeing an act that they put on?
How do you really really know someone? I guess you can’t. You can just hope that you do and trust they are who they say they are.
