In Gridland, the cities are arranged in a 4 by 6 grid:

A-B-C-D-E-F
| | | | | |
G-H-I-J-K-L
| | | | | |
M-N-O-P-Q-R
| | | | | |
S-T-U-V-W-X

A man born in A (and never ventured outside his city) has to visit a man in X but wants to take a detour to get there. He wants to visit every city but not enter any city more than once during his tour. How should his trip go?

Assuming they have telephones in Gridland, the man calls ahead and asks the other man to meet him in city R.  The man then travels the path ABCDEFLKJIHGMSTNOUVPQWXR.  ALSO, I assume that "in X" is a prepositional phrase describing "a man" instead of "to visit."

When the man from X asks why the other man won't just meet him in X, the other man will reply, "Because this is in the tricks category.  This clearly gives me authority to do whatever I want."  The man from X will say, "I think that the trick is that you shouldn't get you want."
