Set Recurring Reminders to Reach Out to Far-Away Friends

Friendships that depend on 'we should catch up sometime' quietly die from vagueness, not from lack of love. A recurring calendar reminder removes the guesswork -- once a month for close friends, once a quarter for the rest, so reaching out never depends on guilt or memory.

When the reminder pops up, send something specific, not just 'hey, how are you' -- a question about something they mentioned last time, or a concrete plan with a date attached. The system does the remembering so the friendship doesn't have to survive on willpower alone.
