I'm left.
But the nuns in my catholic school tried to correct it by making me do everything right-handed (left-handedness was seen as the work of the devil).
So, I bat right. Golf right. Play hockey right when I'm out on the ice, but when I played goalie, I played left handed for some reason. Play drums right-handed (i.e. not the Phil Collins way, though I often switch up and do it anyways for fun and to work on dexterity).
I throw a baseball and football lefthanded, but a basketball right handed. Oddly enough, I kick a soccer/football with my left foot.
When I wrestled in high school/college, I led with my right foot, which made absolutely no sense as far as I could tell.
I write left, but the mousepad is on the right hand side of my keyboard.
