A childhood belief about imaginary friends

i used to have an imaginary friend i think i used to call boso but i'm not sure now when he got excited he used to talk in a really sqeaky voice from the back of his throat when he meant next monday he said last monday and when he meant tomorow night he said last night and he used to say rrrnakkydak which meant lucky duck i met him again years later before my 21 birthday i didn't recognize him at first he sat next to me and his eyes were yellow and then turned blue when i looked at him that happened a couple of times evryone in the room knew there was sombody there but i was the only on who could see him then i asked this guy joe who's that fella with the turning eyes and he asked me if i was a machine and i asked why and he said you must be a machine if you can see him but i don't think i am. and then i started to remember and i held out my little finger and he shook it with his little finger like we used to do
