Robert poop 9:14pmEve are you coming to coffee house my dear? 9:16pmRobert poop yeah mabety 9:16pmEve you should remember that night at the campis household when we were writing poetry I still can’t find that notebook… 9:18pmRobert shit cock. 9:21pmRobert can you see the diffrence ? 9:21pmEve What do you mean? 9:25pmRobert just believe for one second that life is on a beam and one way or the other of every decision of your life will decide the rest of your life each thing you do no matter how simple or small it may seem conducts the symphony of our livves and now that the second is over 9:27pmEve Well, if you think about it, it sort of is, every single choice you make can change your life in one way or another 9:27pmRobert well then why are we here now doing these things? whe could we be other places now doing other things? 9:29pmEve No, because since you are here doing something, there is no other place you should be, because I do believe that everything you do and everything that happens to you happens for a reason, whether it be punishment from you past life or from your ccurrent life, or good karma because of the things you have done. 9:32pmRobert karma is what we are talking about. it has no judgment of right or wrong. it is simlpy the for of consequence, the ever going force that moves though space an time. im comning to the coffee house> ive been coming my entire life. 9:33pmEve yay! I really like people who come to coffee house their entire life I also really like talking to you Robert, you have things to say 9:33pmRobert oh ? poop. fuck facebook. 9:34pmEve Por que? 9:34pmRobert love farmville. porque no? 9:34pmEve Je no ce pas, parle Francais 9:35pmRobert no fuck french just kiddin but i don;t speakcit 9:35pmEve I am really trying to become fluent in French, I want to spend a semester there next year. 9:35pmRobert bonjor 9:36pmEve There’s a start!
