How about me being very excited when I went shopping today?
That sounds great. Why were you so happy when you went shopping?
That was the first time I went shopping for trivial things that I won't even use, it was amazing.
I can understand why you were excited for something you loved to do. Buying things that you don't need is being too extravagant with money and it won't make you any better than anyone else either. You'll still be the same old person you were before but with less money, so you should return the things today.
Nah, I'm going to keep the things I bought since I deserve to have nice things too.
It is okay to have fun shopping but be careful about spending so much in the future. You don't want to not have money when you need it in the future.
