Complaint could easily break the social relationship between the speaker (complainer) and the hearer (complainee). In this case, the complainer may express their negative feeling by choosing the right strategy to deliver their negative feeling to the complainee. There are strategies that the complainer could apply from the mildest one to the most severe one. It helps the complainer to choose whether they want to soften or to strengthen the effect of the complaint.
