Grudges are a storage unit you keep paying for, full of stuff you never visit.

Holding on to old injuries takes continuous space, and the space is not free. The contents are rarely examined; they are simply kept, brought out occasionally and returned, while the rent comes out of attention you could spend anywhere else. Keeping it does not preserve the point you were making at the time.

List what you are still storing and ask what each item is protecting you from. Anything that no longer protects anything can be set down without ceremony or announcement.
