Typically one needs to be able to estimate things oneself and decide freely, whether one participates in something or not. Otherwise one cannot take part with a full heart. If beer makes one social with all without much estimates of how that works, then it at the same time makes one take distance from those social relationship, to not to fully take part and commit oneself to them in the long run.
The Finnish word for "angel" is "enkeli" which literally means "I do not" "Weather" or "No" "Weather" which seems to contain the same wisdom: you cannot ask someone to behave like an angel, if they do not have the freedom to say no and not participate in things that they do not like or agree about. Full support needs the freedom to say No.
