I've learned over time and with bitter experience my dad is terribly sexist. Every time I see him he has something grim to say that erodes my soul and chips at my confidence.
I won't give examples of his crimes but his father -my grandfather- had several girls and my father was his only son. When my fathers siblings went on to have children of their own, they all had girls (7 in total). My grandparents said practically nothing, but then they rarely seemed to at significant events.
When my younger brother was born, my grandfather went to visit my mum in hospital. He had never visited after any of the births of his other grandchildren and presented my mum with a single red rose, then left. 

Cheer me up with some of your tales.
