    "abstract": "We present a simple model for growing up and depletion of parties due to the\npermanent communication between the participants of the events. Because of the\nrapid exchange of information, everybody is able to evaluate its own and and\nall other parties by means of the list of its friends. Therefore the number of\nparticipants at different parties can be changed incessantly. Depending on the\ndeepness of the social contacts, which will be characterized by a parameter\n$\\alpha $, a stable distribution of party members emerges. At a critical\n$\\alpha_c$ an abrupt depletion of almost all parties is observed and as the\nconsequence all the peoples are assembled at a single party. The model is based\non a hierarchical social network. The probability that a certain person is\ncontacted to another one depends on the social distance introduced within the\nnetwork and homophily parameter $\\alpha $.",
