Ambi

I later began relearning everthing the real "right way," which is to say the left-handed way. I became truly "ambi" in most things I do.

Of course, there's the prejudice toward lefties. (i.e. "sinister") Those who are ambi or semi-ambi are just thought of as strange. In my case, it rather nicely fits my personality to be semi-ambi, as I also have other odd talents and display inginuity and intrepidness.

And the rest of many of you, are ambi! I always thought *that* was way too cool.

This with the sickle illustrates the frustration of lefties, but also ambis when their right hand gets tired and want to switch over.
