8. When did she buy that Condo...surely not during the Boom? And is her job secure now?
I worked with a person from UPS (United Parcel Service) who had been cut after 15 years service...and herpension and benefits were cut so she went into Real Estate Sales before the boom. We know our US Postal Workers (different from the UPS workers) are now going to be cut, with branches closed.
I hope your sister well and glad she was somehow successful....but, your post doesn't seem to jive with encounters I've had with people who worked as "Cocktail Waitresses" AND in an area like Miami Beach which has always and still is hugely expensive and USPS who was driving her route extended in the last few years working more than an 8 hour a day to keep her job.
Maybe you could give more info about the time period your sister was so successful in that might clarify why I find your post not so realistic compared to the people I know and have known and their own experiences.
