I have black and orange running through my veins. It is genetic.
My history with the team goes back long before I was born and the team first came to San Francisco. My Great Grandfather immediately became a fan and he turned my Great Grandmother into one. Well into her 80's, decades after he passed, she would take the bus to Candlestick Park or watch the games on TV or listen on her transistor radio. I remember her keeping score of every game in a steno pad. When she had a heart attack, the doctor forbid her from watching or listening to the games because she got too excited.
