Not sure it should be considered that shameful. Bedbugs have been found in some of the best homes in this country. Lot of high class hotels have had some issues. This isn't really an issue of living in filth. Seems odd that a hospital can't treat sick people.
Her home is infested and she’s bitten up. Didn’t sound as if she was doing anything about it at the time. Besides that, if I had this unfortunate infestation I would not go complaining publicly that I wasn’t treated because of it. Who the heck wants large groups of people to know that you have a bedbug problem?
I see a new Strauss-Kahn defense in there somewhere..."The bedbugs made me do it!" Or, "The bedbugs transferred my DNA to the maid!" Etc.
