A friend by definition is someone you at one point spent over 12 hours a week socializing with closely and had at least 7 major bonding moments over a one year period. After that vesting period you are allowed to drop to just 6 hours a week and 3 major bonding events yearly for the next 2 years. After that you can run the friendship in maintenance mode using the momentum gained and simply reach out for lunch once a year. But if you miss a once a year lunch 2 years in a row, or if your current group of friends grows twice in size in a single month, that work friend will be put into essentially a PIP. You inform the friend of the need for increased socialization and let him know if a major bonding event does not occur, or if a decrease in rate of friend acquisition does not happen, he will be terminated and sent his remaining funds via an ACH check.

It's been this way for years
