This summer, I took my niece shooting for her very first time.* Her shots were all over the place, everywhere except on paper. I noticed that she was using her left eye so I told her to try shooting lefty. Viola! Every shot thereafter was centered perfectly side-to-side but a little high. She got better with each shot but then got bored so she never really zeroed in. Aside from shooting, she does everything else righthanded.
* She had fun for ten minutes and was bored thereafter. I guess we don't have another enthusiast in the works. Sigh....
