Dinseynut was correct.... I apologize... I thought I responded to the answer yesterday....
Ok you live in a house that is square.... It has four windows... one on each side......the question is....any window you look out of faces north.....wher is the house?.....secondly you look out of the north facing window and see a bear go by..... what color is the bear?.....
A question to think about (but not answer)....
If a mirror reverses left and right... why doesn't it reverse up and down...
If common sense is so common.... why do so few of us have it...
If a frog... oh neve mind....what about the bear?
