Devoted mother, My favorite human.
My most trusted confidant and an ardent supporter of everything I did in my career, has passed.
The most open, warm person I have ever known.

Her passing has left a huge hole in our lives as a family.
I miss her hugs.
She was a unique character, always seeing the sunny side of life.
She had a wicked sense of humor and always laughed at my bad jokes.
Mum is our best friend and were honoured to have received a love like hers.
