...and you'll be ostracised if you'd rather not mingle with hundreds of people, many of them likely strangers to you. Rejecting Asian social tribalism makes you a pariah.An example- Weddings in SouthEast Asia, have almost 1000 guests! (Only a couple of events are reserved for small number of guests and then it is usually very close friends that are invited, but they are invited. )These are not family only...a lot of them are friends...of the people getting married and the in-laws as well...but this is not an example of friendship..just an example of how "loose" the concept of family usually is..even good neighbors become family.
Again, in those cultures, food is always shared regardless of how little or how much one has.
Personally, I tend to end up doing friends one at a time. Since family + friend means more than one person, I tend not to mix the two.
