I am left handed at all things, but I was forced to write with my right hand (and Copperplate..) since I was a child. That's the only thing I do with my right hand.
That means that I should be able to do everything with my right hand, in principle. And I can; that is, for example drawing I can do right-as well as lefthanded, but I don't.
For the thing is: it doesn't feel 'right' to do it with my right hand. That is not my 'good' hand. It feels completely unnatural to me.
