when you earn a little extra money,is it better to spend your money or to save it

问题描述:

when you earn a little extra money,is it better to spend your money or to save it
这是一道托福口语题,我选的是save money ,但只想出来一个理由,就是防止未来有意外发生
哪位大仙能再帮我想个理由?最好用英文的.

To save money:
1.for a rainy day.
2.for a large purchase.
3.for turning student loan.
