Sinister is a word meaning the left side.
I know someone who calls herself Ambisinister
because she has two left feet.
My husband's a lefty.
They tried to get him to switch hands when he was a kid,
but he would just put his fork back in his left hand.
He and my left handed sister say, "Only lefties are in their right mind."

Youth lives by personality, age lives by calculation. -- Aristotle on a calendar
