How right you are...so long as we know what they mean, that is all that matters...aside from having cared for my mom with Alzheimers, I worked for many years in nursing homes, always prefering to work with the Alzheimers residents...often folks with Alzheimers lose their ability to use the 'correct' word for something and its up to the caregiver to know what they mean, regardless of what words they may use...
