Life's simples

If you are 2nd best at reading somebody, what does it show?
If you can understand someone so well that hardly any explanations are needed, what does that mean?
Is it always good to have someone who can understand you so perfectly?
Does this only lead to higher expectations of that person, and likewise more complications?
If you hang out too much with a person, such that time passed in reality is much shorter than time passed in feeling, does it account for anything?
If you feel so comfortable with someone would you expect something more to happen?

If all these questions could be answered, wouldn't the world just be a simpler place?
