There's ups and downs of any job. If you worked at the post office, there's ups and downs. You have your good days, and you have your bad days. If you're a housewife, you have your good days, and you have your bad days.
I know my spirit is not mean, and I have a very good spirit and a funny spirit.
I think it's good that I get scared because, if you never get scared, you don't have any need for guts.
