I think that’s it. Maybe that’s how we know when a relationship is real. When someone else previously unconnected to us knows us in a way we never thought or believed possible.
It seems to me that in the context of life and existing and people and relationships and work, being sad is one correct answer. It’s truthful. Both are right answers. The more we tell ourselves that we should always be happy, that happiness is an end in itself, the worse it gets.
