First: I don't think you can always indulge your sister's temperamental behavior of not working. To tell the truth, everyone doesn't like doing housework, but you can't help it. You can't mess up your place, so you can't live comfortably. Your sister can't stop doing housework because she is moody and doesn't like it. If everyone in the family is like her, no one will do housework.

Second: if the family always tolerates her, pampers her and pampers herself, then after a long time, her own thoughts and behaviors will change, thinking that these should be done by you, not him, and then go out to other people's homes. This idea will accompany her, but in other people's homes, people will not tolerate her, and they will think that she has no tutor, no upbringing, and doesn't even understand the most basic etiquette.

Third: everyone likes leisure and doesn't like work. After returning home, everyone is willing to lie in bed, play mobile phones, and some people cook and eat. However, it is always like this, and reality will not allow it. Occasionally, if you spoil her, you will ruin her instead of helping her. I hope you can understand this and guide her to work hard slowly.

That's my answer. I hope I can help you.
