I completely agree with Perpetuallysad. If you're living on your own and working 2 jobs then it's none of their business what you spend your money on. I could see if you went bankrupt or are a shopaholic, then their advice would be justified. The only thing I can think, why they're doing this, is perhaps they have struggled financially and are trying to teach you from their mistakes - is this the case? If you're on your own, then it's none of their business.
