The innovation of a pioneer

I just spent an entire day working on a document in the Adobe Reader Touch app, highlighting and making comments on a study and at the end when I was finally finished, I went to close it and - what do you f*cking know - it did just that. No prompt to save it. Are you f*cking out of your mind? Not a single other application that I've come across that does ANYTHING (not just viewing pdf files) - that allows to edit content in any way - does that - and you decide to be the pioneer? What's wrong with you? It doesn't matter that it's a free app, this is almost maliciously stupid. F*cking wow. F*cking w-o-w.
