One day two friends, Paul and Ron met in town. Paul said, Ron it's good to see you."
“ How can you see me when I'm not here？” Ron asked.
“ What do you mean,you’ re not here？” Paul asked.“ Of course you're here.
No, I'm not, "Ron said, " and I'll bet （打赌） you ten dollars that I can prove I'm not here. Then we can enjoy a good dinner with the money
“ All right，” said Paul.“ Ten dollars. Now prove you're not here.”
“Easy，” Ron said“ Am I in Hong Kong？”
“No.” said paul
“ Am I in paris？”
No said paul
If I'm not in Hong Kong and I'm not in Paris, "Ron said，"then I must be somewhere else. Right？
“ Right，" said paul.“ You must be somewhere else.”
“ Exactly，” said ron.“ And if i'm somewhere else i can' t be here can I？ Ten dollars, please.
Yes, I admit you are not here. But who should i go to the dinner with since you are not here？ And who should I give the money to？
