【正文】 thats two isnt it What else would you call us We cant ever e together again But Im talking to just one of you We both can hear you Which one answers Nicholas touched the right side of his chest with his right band Me I do They told me it was the left side of my brain that one has the speech centers but it doesnt feel that way the nerves cross over ing out and its just the right side of me I talk Both my ears hear for both of us but out of each eye we only see half and halfI mean I only see whats on the right of what Im looking at and the other side I guess only sees the left so thats why I keep moving my head I guess its like being a little bit blind you get used to it The girl was still thinking of his divided body She said If youre only half I dont see how you can walk I can move the left side a little bit and were not mad at each other Were not supposed to be able to e together at all but we dodown through the legs and at the ends of the fingers and then back up Only I cant talk with my other side because he cant but he understands Why did they do it Behind them the monkey who had been following them said He had uncontrollable seizures Did you the girl asked She was watching a sea bird swooping low over the water and did not seem to care Nicholas picked up a shell and shied it at the monkey who skipped out of the way After half a minutes silence he said I had visions Ooh did you They didnt like that They said I would fall down and jerk around horrible and sometimes I guess I would hurt myself when I fell and sometimes Id bite my tongue and it would bleed But that wasnt what it felt like to me I wouldnt know about any of those things until afterward To me it was like I had gone way far ahead and I had to e back I didnt want to The wind swayed Dianes hair and she pushed it back from her face Did you see things that were going to happen she asked Sometimes Really Did you Sometimes Tell me about it When you saw what was going to happen I saw myself dead I was all black and shrunk up like the dead stuff they cut off in the pontic gardens and I was floating and turning like in water but it wasnt waterjust floating and turning out in space in nothing And there were lights on both sides of me so both sides were bright but black and I could see my teeth because the stuffhe pulled at his cheeks had fallen off there and they were really white That hasnt happened yet Not here Tell me something you saw that happened Men Without Women Ernest Miller Hemingway was born in 1899 at Oak Park a highly respectable suburb of Chicago where his father

wounded Returning to America he began to write features for the Toronto Star Weekly in 1919 and was married in 1921 That year he came to Europe as a roving correspondent and covered several large
