I find it interesting that one, to be “sinister”, is to be left-handed; two, that “sheep to the right, goats to the left”; three, within the Pagan community, there is a “right hand/left hand path, i.e., light vs dark”; four, I was born a leftie, like my late mom, and was switched by her, which, in turn, messed up my balance, and explains why all my biological maladies showed on my left side!
I once had a muzzy boss. Not only was he freaked that I am female but also a lefty. He could barely tolerate being in the same room with females which caused all the females to quit. I tried to outlast him but was the last to finally put him in my rearview mirror. One of the final straws was when I tried to give him a watermelon from a client. He jumped away like I was handing him a rattlesnake. Seriously, jumped several feet back with terror and disgust on his face.
