Explain the concept of gunny-sacking

What will be an ideal response

Gunny-sacking is reminding people of past mistakes or issues and linking them to the current situation. If it is used as method to bring old, unrelated issues into a discussion (or argument); it can result in a negative situation where the person becomes defensive. It may be helpful if supportive communication is used to describe past incidences of the same negative type of behavior if it reveals a pattern that needs to be addressed.
