My daughter had a stroke at birth, now 13 going on 14 years later, she still has problems with her left hand. Being a baby it was a easier transition since babys dont know anything, they adapt quicker than an adult. She can use her left arm to an extent, but when she was smaller and I would take her to a pond to fish, I would bait her hook and everything, got her a zebco 33, the one with the push button, she got where she could throw it pretty well, when she would catch a fish she would stick the butt of the rod in her chair and crank with her right hand. She would loose a couple of course, but to a kid, the excitement is seeing the bobber go down, right? If she would catch one too big she would just hollar Daddy! and I would help, she didnt mind at all. Shes a straight A student now and has a wonderfull ability to draw, and wants to be a artist or designer after college. It is managable for her to fish, but, you will have to help out also. In time it doesnt really matter if they catch anything or not, just being out there. Just remember its all about them, and your friend is lucky to have you as a bud. Good luck and God bless.
