Results: Wants vs. Needs

I have a friend who is always complaining about her money situation, but yet goes out to eat almost everyday, buys prepared foods often instead of cooking, pays to get her hair colored, streaked, or braided, and gets her dog groomed regularly. She also has $10,000 on her credit card and makes just the minimum payment! I could save her at least $100 a month or more! But I keep quiet, except to tell her to please put away something from each Social Security check and build up some savings. Do you know people like this, who have trouble with knowing the difference between wants and needs?
