I have to admit that whenever I glare at someone while walking down the street, whether for driving like a jerk or staring at the kilt, I always find myself feeling guilty. Almost without fail, I end up thinking, "If I am being rude, am I representing the kilt poorly to strangers?" I don't think this way when wearing a UK, but almost always with a tartan. Actually, depending on location, I find that I'm better off putting on sunglasses and a perma-glare, just to avoid an incident with locals; my wife just finds the idea of me trying to look tough kind of humerous. Oh well
