Is AUTHOR wrong in the post ? POST : This literally just happened but I’ve made sure to calm down first before doing anything. So, basically, my mum had a friend visiting from overseas last week and I hung out with her daughter too so we got along fine and I didn’t mind the visit since it was only for a few days. 

During one of the days, they’ve decided to go out to the casino and left me to look after the daughter and their younger son (who was around 3). I was fine with this but before they went out I let her friend borrow my nice boot heels that went over the knees because she didn’t have any shoes other than trainers. Please note that I ONLY LET HER BORROW IT. I didn’t say she could have it. She didn’t ask to have it. Nothing. Just borrowing. 

Then a week later (today), I’ve found out that she has given her friend my heels, the heels that I have paid for with my own money. My mum didn’t bother to ask me if her friend could have it, she just gave it away like it was hers. She didn’t even bother to mention it for a whole week. 

I really like those heels, I can’t get another because I’m a student with two part time jobs just to support myself through university. I’ve never asked my mum for any money and everything I have was paid with my own money. I had plan tonight and was planning on wearing those heels but now I can’t. She called her friend to keep it for me but I still don’t know if I’ll ever going to get it back. 

I got angry because when I confronted her, she didn’t care and basically just go “oops”. I told her about the plan tonight I had and she was literally just going “oh well. Tough luck.” (Translating her reaction to English equivalent as we’re not English)

So AITA for getting angry at my mum over the boots/heels? Am I overreacting?

TLDR; My mum gave away my favourite heels to her friend from oversea without asking me nor mention it until a week later. When confronted, she doesn’t care and I got angry as I’ve paid for them with my own money. AITA?
