Hey now- that's how I met one of my best friends! We had a knock-down, drag-out fight (over what? I don't remember) and while sitting at the principal's office to take our lumps, became friends.

Re: Concealed weapons, or carrying them in general... Vimes, one of my favorite literary characters, has just discovered a one-shot crossbow, basically a tube with a powerful spring and an arrow...
"This is not a weapon. This is for killing people," he said.
"Uh, most weapons are," said Inigo.
"No, they're not. They're so you don't have to kill people. They're for... for having. For being seen. For warning. This isn't one of those. It's for hiding away until you bring it out and kill people in the dark."
-The Fifth Element, Terry Pratchett
Just be careful and remember not to pull anything you're not prepared to use, and preferably able to use without hurting anyone.

As for idiots making skirts comments, why not ask any young ladies in skirts at the bar to help you out with showing the differences? "Now, this is an apron, you'll notice her skirt doesn't have one. These buckles? Two on one side, one on the other, I see you, miss, have buttons. This is called a tartan, that's TAHR-tin..." Kill them kindness, or bap them with boredom!
