If you all agree that being Scottish is the best, but you have different ideas of what defines Scottish, then are you really agreeing on anything?
It's like, uh... if I were to say "My favorite color is blue!" and someone else said "Hey, mine too!", but I'm thinking navy and he's thinking of some sort of bright cyan, then do we actually have anything in common? Or do we just think we do because we're using vague language?
