A:you are annoyed because your brother sister is always borrowing your things without asking first. Explain how you feel.
B:You can't see what the problem is. Brothers and sisters don't have to ask each other first if they want to borrow something.
Можно по-русски)

- I hate her!

- Whom?

- Daisy! My little sister. I was searching for my new blue jacket this morning for about an hour and where do you think I have found it later? On her! She just took it without even asking me! 

- Even elder sisters sometimes borrow clothes. It's not a big deal.

- It's a big deal as it is not the first time when she borrows my stuff without any permission! And it's not just clothes. Last week I found my lipgloss and mascara in her bag! How about that, huh? It's the same as stealing! 

- No it's not. 

- Yeah it is! Who knows, maybe she didn't want to give them back later. 

- She is your sister. Brothers and sisters don't have to ask each other first if they want to borrow something. And also don't forget that she's just ten years old!
