The photo is not of me, it is my father (aged a few months) with his grandparents. My great grandmother was a sour tempered, vain and unpleasant woman who complained unceasingly about everything. Her life was hard (they were farmers in NE Victoria), but she was quite well off, and if she had been more pleasant, she would have had a good life; as it was, people avoided her like the plague. On the other hand, my great grandfather (who died before I was born) was greatly loved, and everyone who knew him smiles when they talk about him.
Every family has people of both types; fortunately, nearly everyone in mine is positive, outgoing and friendly. My father's other grandmother was like that- she is the one I aspire to being like.
