The person offering another chance is allowed to keep a practical safeguard.

Forgiveness and prudence get treated as opposites, so anyone who keeps a precaution is accused of not really having forgiven. In practice the safeguard is frequently what makes the second chance possible: the separate account, the shorter commitment, the arrangement that limits what a repeat would cost. Removing every protection is not a deeper form of trust, only a larger bet.

If you are giving someone another chance, decide what protection lets you do it with an open hand, and keep it without apology. If you are the one being given it, treat their caution as the price of the door being open.
