My friends kept asking me how water softeners work, but I really don’t know how they work because I don’t have this product and I have never try it before. He don’t know how to use Internet, and need my help to help him find information about how water softeners work from Internet, then print out and send to him. He seems like my boss, but actually I didn’t get paid from him. Anyway, I know he will appreciate my work. I hope when I need his help next time, he will try his best to help me back. If not, I will going to “kill” him!
