Guys my younger sister is smoking something, what could it be?

Hi, i 18m and my cousin sister 14f, is asking me to come with her to travis scot concert. I asked her that are you serious, coz travveling to another city for just 1 concert is stupidity. She said she is serious, so i asked that will she sponser my food, acomodation, travel. She replied with, dude it will just cost 80k + tickets surely your parents will lend you that much, like wtf how could you use the word "only" with a figure as big as "80k". And i am still in shock, and wondering that wtf is she smoking. Kya bolu usse?
