My answer to question 4

Okay, there are two problems here. First of all, somebody is nicking money in your family, and second of all, your sister seems to be in need of help. You can still not be sure that your sister is stealing though, but there might be a chance it is her. And you’re saying you’ve tried to speak to your parents, but they won’t listen. Well maybe it’s because they have something to do with it.
For you to be able to figure out who’s stealing, you should try to talk to your family members again. Try to talk to your sister and make sure she knows that you’ve got her back and that she can always trust you and tell you the things that are happening in her life, and just be supportive of her. Then, talk to your Granny. Ask her what’s stolen and what she thinks. Your Granny can help you figure out things that matter in this investigation.
At last, you should talk to your parents. Make sure they get what’s going on in your family and ask them if they have anything to do with it. And also, tell them about the situation with your sister and that they also have to try to talk to her. And if it’s your sister, then helping her with the problems that are going on in her life will maybe lead to the fact that she also stops stealing money. Talk to your sister, and make sure your parents do it too.
