Im taking some cooking classes and its time for final exams, I buy some cake molds online.

One of my classmates is gonna present the same cake than me for the final, but with a diferent flavor like chocolat

She discovered I bought online molds and private message me like " Hi Im nora (fake name) from class you got the cake molds? When I told her that I did buy some online she started telling me that she wanted the squared shape ones (i wanted the rectangle ones) and how many I buy.

I told her that I didnt remember well how many I bought, then she asked me if I have spare molds to sell her like 8 or ten because she didnt find any.

I told her no because I didnt even have the molds yet (they ended up being delivering now after 3-4 days at late night and a little different size but still good to use)

My mom thinks AITAH, that I was rude and selfish,that Im always like that, a difficult person that cant take opinions or undertand others, I think she is just dramatic but still AITAH?
