history: My younger sister is constantly going to concert after concert, travelling across the country. It's not that I want to go to so many concerts--I just wish I had all the money she has to be able to afford it!
current: My little sister has been going all across the country this summer, spending lots of time on money on pop concert after pop concert.
next: Interesting. How do you feel about it? Do you find it fun and interesting, or wish she were more responsible with her money?
