My sister, brother and I literally owe our lives to Bernadette, but she didn't just bring us into the world; she dedicated everything she had to showing us how utterly thrilling, friendly, creative and fulfilling that world could be. We all owe her our morality and worldview and optimism and very identities.
Her unconditional love and confidence in her children, her support of every passion and hobby, her example of immediately helping those in need without being asked; her instinct to praise good deeds rather than punish the bad; all shaped us to the core. We face every moral dilemma - consciously or subconsciously - with the question "what would Mum do?" The answer is always the most selfless path.
Not everybody gets this privilege, which is why she extends her honorary family to practically everybody she teaches or befriends. There are hundreds and thousands of people out there tangibly better off because she's gone out of her way to make them feel loved. She didn't just teach us the world was good; she's actively making it better, each and every day.
She also purchased Radiohead's "OK Computer" before it was cool. I feel compelled to add this fact.
