premise: Guy playing the guitar on a bench with another man watching him.
hypothesis: The guy teaches his new guitar tricks to his friend.
explanation_1: The guy doesn't have to be teaching and could just be playing. Also the other man could be someone other than just a friend.
explanation_2: The fact that a man is watching a guy play guitar does not mean that the player teaches his new guitar tricks to his friend. Just because one person watches another does not mean they are friends.
explanation_3: Even though the man is playing guitar to another man, it does not mean that he is teaching him new guitar tricks.
