On Knapp's Relationship Model, he pointed that most new relationships are on the Experimentation Stage. People try to look for a relationship that fits them. This is the time they try to get to know each other and analyze if they have some common interests that they like to do or not. They try to think all the information, the experiences and feelings are enough to keep the relationship.
This stage is open for possibilities for them, this stage will be a basis for accepting a person, or go on and search for someone that they would have better chemistry.
