The Magic Doorway.. [_]

[tunsty]

A simple idea (aren't mine always..)
I have a magic doorway, through which, only certain things can pass..(some peculiarity about the object/thing)

I will give a couple of examples of objects which can/cannot pass through, then you can all make wild inaccurate guesses of your own, until someone stumbles upon the answer.. at which point they can think of their own 'peculiarity'.




Here goes:

Sheep can pass through, but cows cannot.

Scottish people can pass through, but the English, Irish and Welsh cannot..



You're welcome to ask more..
