Explain the concept of gunnysacking

What will be an ideal response?

Gunnysacking 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), t 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.
