Definitely not. This is a very private and inappropriate situation within a family context. We should respect the privacy and dignity of others, and promoting or discussing such a scenario is unacceptable in a civilized society.
Another reason might be that they are not following the rules. For example, if there is a rule that they can't watch TV until they finish their chores, and mom catches them slacking off and watching TV instead, she would have to step in and remind them of the rules.
Well, it could lead to a scolding. Mom might be really angry and ground them for a while. For example, if they were doing something naughty like sneaking cookies before dinner.
A sister might encourage her little brother to pursue his dreams. For instance, if the little brother loves painting, the sister will praise his works and tell him that he can be a great artist one day. This simple act of encouragement can have a huge impact on the little brother's self - confidence.
First of all, she should keep it confidential. Then, if she feels it's necessary, she might approach a trusted adult like a parent or a counselor who can handle the situation in a proper and understanding way, guiding the brother about appropriate behavior in a non - judgmental manner.
Well, perhaps the 'big brother' and 'little sister' had some bad experiences at the ATM. Maybe they faced long queues, or the ATM malfunctioned and ate their cards. It could also be that they were in a hurry and the ATM was extremely slow.
I'm not really sure specifically what the 'ertioca archives' are. But stories about a little sister and brother can be very diverse. They could be about their adventures together, like exploring a mysterious forest near their home. Maybe they find a hidden treasure or meet some friendly woodland creatures.
One possible story could be that during a family wrestling match in the backyard, the little sister shouts at her brother for using a 'dirty move' and shames him in front of their parents. This makes the brother feel embarrassed and he tries to defend himself by saying it was an accident.
The brother could be really good at math and he helps his little sister with her math homework. He patiently explains the concepts like addition and subtraction to her.
They could go on a hike in the forest together. Discovering a hidden stream, they might have a great time skipping stones and looking for little fishes.
