The wedding house that she kindly lent to her cousin for a temporary stay became a free hotel for her husband's family of eight. When it became a matter of course that "the dove occupies the magpie's nest", and when a strange old lady in my home asked "Who are you looking for?", I finally understood that kindness must have thorns. There was no quarrel or entanglement, I just silently changed the password and let those greedy smiling faces be trapped in the space that belonged to me. Faced with the accusations, I chose to speak with the law and evidence. This is not ruthless, but the most gentle defense of one's own bottom line.
