Being tired and stressed and thus not modulating your voice tone or facial expression appropriately when responding to a child who is demanding attention while you are trying to do some other chore necessary for life, e.g., cooking dinner, etc is itself abuse if done repeatedly over many years. If you are not immune to stress and fatigue changing how you respond to people and external stimuli then you will be an abusive parent, and you are an abusive partner.
