Sheri wonders sometimes if there really is a definition of Dementia and Alzheimer's. It is so different for everyone. People seem to always know someone who has it, but it always seems to be just a not so important kind of an illness. The reality for Bob and "Al" is that Bob could not function on his own without some one like Sheri in his life, and yet recently, awoman moved her 90 year old mother into the community that Sheri manages under the impression that this woman would be living with her mother, but that does not appear to be the case and is now leaving her home alone. Sheri knows that some 90 years olds may be capable of being by themselves, but after spending some time with this person, it does not take a rocket scientist to know SHE should not be left alone. Very frustrating in deed. Sheri will do whatever is necessary to keep this woman safe. She has done it before... she will do it again.
