congratulations
and the mail proves my point. you can pretty much ignore the case system and yet be understood (beim erstmaligen Kauf instead of bei seiner erstmaligen Kauf, nobody would even say bei deinem erstmaligen Kauf (correct at least), not to mention the fact that you have to buy (kaufen) something (direct object required), usually. though there is the Einkauf (usually refers to what you buy at the grocery store) and the Aufkauf (taking over an enterprise or buying everything that is available of a commodity). meh, you stopped reading a couple of lines ago right about the time when I stopped making sense so....)
So you guys have trouble correctly speaking your native language ?
. We are far too superior (tm) to only use one simple version. You have to improvise. Each attempt of communication is a new adventure
