Two studies were conducted on the rules of relating communicated in the soc
ial network interactions of young adults. Study 1 involved 68 university st
udents who completed a two-week diary recording interactions with others in
which rules for conducting relationships were communicated. In general, ru
les for relating tended to be communicated among same-sex dyads or triads t
hrough advice-giving, sanctioning, and gossip. Rules dealt primarily with r
omantic relationships (qualities of desirable/eligible partners, and how to
initiate, sustain, and dissolve relationships) and friendships (how to con
duct them). Study 2 was a survey administered to 127 university students on
the extent to which they followed these rules, the degree to which they wo
uld receive negative sanctions if the rules were violated, and whether they
perceived the rules to be gender-linked. Although several rules were perce
ived to be gender-linked, few sex differences emerged on perceived sanction
ing and on reported rule compliance. In general, rules of loyalty, openness
/honesty, and respect applied to both friendship and romantic relationships
