Jillian Rennie was left feeling overwhelmed on Wednesday after members of the public flooded her with birthday cards.
Ms Rennie has dementia and Alzheimer's and ever since she was a young girl has had a passion for writing letters to people all over the world.
She often finds herself writing to her family, most of who live in Australia, her pen pals overseas and her celebrity favourites - Mick Jagger and Prince Harry.
As a birthday treat and surprise Ms Rennie's daughter Christine Burns posted on Facebook just before her mum's birthday asking people to send in cards or notes to make "her mum's day".
"My mum couldn't believe it getting all these cards she was so excited and so happy, it really did make her birthday for her."
