If you have anyone in your family or close to you who has developed Alzheimers, then this part of the storyline may perplex you.
I don't recognise any familiarity with Sue Johnston's character and the disease whic has destroyed my Mum for the last 6+ years.
Not reality, and offensive.
Unfortunately yet another attempt to use an Alzheimer story line without fully understanding the reality of a devastating and merciless condition.
