The stage of relational development is Experimentation, in which people interact by disclosing information about themselves. In this stage, individuals make small talk to identify common interests. Furthermore, exchanges are kept friendly and informal.

I could also try to have more profound dialogues in order to move to the next phase, Intensifying. Besides, I could cause to talk to the person more frequently and give tokens or gifts as a manifestation of greater affection.
