Re: Lefties...
Back when my girl Whirls(gig) was a blonde....she had "TGIF" marked on her shoes. All of her lady friends suggested she was putting a bit too much emphasis upon the "Thank Goodness It's Friday" thing....to have Gig remind them...."TGIF" simply meant "Toes Go In First".
I don't know if that stemmed from being a lefty or a blonde however.
