I'm a nanny. The landlord's daughter came back the day before yesterday. Her daughter is very disrespectful. She also said that when she was old, she became a nanny and lived in vain. What should I do? This disrespectful attitude of the master and daughter really makes you feel bad. She has no respect for people. If she is the shopkeeper, maybe we won't serve her, but the shopkeeper is not her. Let's just do our job. The fact is that people who don't respect people are in vain! People who live to do things beneficial to themselves and others will not live in vain!
