This is a very good example to show that she has taken the use of sarcasm to explain her side. Texting ironically kills romance majorly because one cannot deliver the exact emotions or express the way he/she feels through a single text and at times these texts can be misinterpreted too resulting in utter chaos.
Yes, I do agree with Kutcher's observation as today we get to communicate within seconds so easily that it kills the charm of a relationship. One gets absorbed by technology in such a manner that they forget one needs to have flaws, be physically present, love, touch and show affection in order to keep the spark in a relationship lightened. Texting cannot convey the vulnerability and the bags of emotions one carries within himself.
I believe that the incident that happened with Karen was not just an accident but something intentional. I agree that accidents do happens and we humans do make such blunders on regular basis but making a PowerPoint presentation that contained such content public is just an act to acquire publicity at a very cheap cost. One gets quite alert when handling such explicit content and making it go viral and calling it a mistake is merely covering up for the thing. Hence in my views, it was intentional and just attention seeking.
http://www.washingtonpost.com/wp-dyn/content/article/2007/09/14/AR2007091401972.html is the URL I have used for my module one essay. The reason I consider it to be reliable is that it refers to a magazine/newspaper that is published and its online version is available too. Furthermore, the author's name is mentioned so that the credibility of the content remains intact and any for any further queries an email is providing too.
