The responsibility that no longer fits deserves a conversation before it becomes a quiet source of neglect.

Commitments outlive the circumstances they were made in. Your hours change, your health changes, the thing itself grows, and a duty that once fit comfortably starts arriving as dread. What usually follows is not a decision but a slow fade: later replies, thinner effort, and other people quietly absorbing what you stopped doing.

If something you agreed to has been sitting heavily for months, say so to whoever it affects while you still have goodwill to spend. Handing it over on purpose is far kinder to everyone than letting it fail slowly.
