Explanation:

When Jane sat down with her partner Pat to discuss a disagreement over finances, Pat responded by bringing up old issues and problems that had long since been addressed. Pat is engaging in kitchen-sinking. Kitchen-sinking is a practice in arguments or conflicts whereby instead of an individual involved in the conflict to dwell on the issue on ground and bring up possible solutions, brings up old resentments and issues that have previously been addressed. This involves listing out all the previous mistake of the other person in order to win the argument while not addressing the issue on ground. The aim is simply to win in the conflict/argument or put the other party down by stating their previous shortcomings which are unrelated to the current issue.
