Sinister
The Latin word for Left is Sinister. Betcha didn't know that!
My grandma was lefty, two eldest siblings are lefties, my son is a lefty, that makes about 1/4 of my family evil!
Conversely, the western world reads from left to right, while the oriental world reads from right to left. (Arabic, Japanese...ever try to read a Manga? I go cross-eyed!)
