Its actually the phase which is most difficult and also the most energetic one after the long search we will come to a point were the list will be short one or two as our close frnds and others as other circle and might be happy spending time. And then that particular one will be becoming the most important person in chat..But it also makes more issues because we might be in the doubt that is she ya he has same feeling as we have towards her/him.And is she in relation with some one else. When she is online for long time and she never sees you and so on this face is like mixture of tension and also happyness she/he might tell some clues that you are too important. And another might be distance and she/he might be similarly having tension and so on. Actully we might have found the person whom we are comfortable with at this phase chances of becoming the unknown is more will tell the next phase tomorrow which will make a conclusion....
