I'm not ambidextrous, but I use both hands equally. Tasks involving fine motor skills are done with my left hand, and tasks involving power are done with my right hand.
So I write lefty and can barely hold a pen righty. Tooth brush lefty, hold a fork lefty, etc.
I throw righty and throw like a girl lefty. Kick righty, open jars righty, etc.
However, for reasons I can't explain, I carry things in my left hand. If you give me three books, I cannot grip them at all with my right hand. I have to carry them lefty, even though my pattern indicates that it should be righty.
My past posts echo through the hallowed halls of Chiefsplanet.
