Conversation is 2 way. It's not dependent only on yourself. It is inter-dependent. It also depends on the other person. We can't predict how the other person will react. There is an unknown factor in every single conversation. Hence, every conversation is an adventure.
When we converse, we are playing an intellectual and emotional match with the other person. It's a match where no one needs to win. The match takes place for the sheer pleasure to play. This makes every conversation an adventure.
Often, when we start a conversation we have not been able to gauge the calmness of the mind of the person. Sometimes, the person is upset at something else, and in your innocence you have started a conversation. You run into rough weather. Every conversation is an adventure.
