Friendships

The Friend Who's Always Got It Together

Quietly reliable, financially sorted, never the one asking to borrow — friends notice, even if the Sentinel never mentions it.

Lending and Owing

Precise and fair — a Sentinel tracks exactly what's owed, calmly and without resentment,

because that's simply how they keep things.

Group Money Moments

The one who builds the spreadsheet for the group trip that nobody asked for, and that everyone ends up grateful exists.

What Friends Need to Know

The structure isn't a request for recognition. It's just how a Sentinel operates — using it, not thanking them for it, is usually appreciated more.
