Left hand thread lug nuts on driver side

LOL funny story, I bought my 70 Swinger, got it home , was taking the wheels off. I broke a stud on the drivers side. I called the guy who sold it to me and said "what did you do when you put the lugs on, them things are tight" he 's like " Ya know what? I think those are left hand threads..." Im like "oooooohhhhhhh......." :)
