I can see where your coming from. To an extend, this is true in some situations, but in a lot of others, they are facts, not perceptions. If I see someone treating me differently compared to the way they treat others, especially if it is negative, I really don't think I am just perceiving that they may not like me the same away as they like others, it is a fact, due to their behavior and actions, that they clearly may not like me, or at least not like me as much as they like other people they know. Some people who are overly optimistic will say that even if someone treats you differently, especially if it is in a negative way, they still really like you. I believe that form of thinking is too optimistic and leads to disappointment and may even cause others to think you can't take a hint. I like to see things for how it is and if others really like me, then they should show it through actions.
