Don't you get upset when your siblings take your things without asking?

Do you think it is wrong to get upset at your sister because she takes something that is yours without your consent? Like most of the things I have, I have paid for them!! I came home from a trip, look at my desk and realise it looks weird. I check for the missing thing and see it's my desk lamp. I go to my younger sister's bedroom and see she has my lamp on her desk. I AM SO UPSET! I shouted at her why she had it. She said, it's because I needed it.

WELL GO BUY YOUR OWN STUFF!!!!

I was so angry and was about to insult her but just remained quiet. DONT TOUCH MY THINGS WITHOUT MY PERMISSION!!!!!!!!!

I am very upset! I want to cry and hit something!!!! 😭
