The case system is a tool, Nichole. At first it might be hard to handle, but once you learn it you'll be glad that it exists. In my opinion the Russian grammar is much more flexible than the English grammar, thanks to those crazy cases.

The hardest part for me is feminine singular adjective endings: four of them are identical, and while that makes it easier to learn, it also makes it harder to comprehend: Sometimes you practically have to guess from the contex whether it is genitive, dative, prepositional, or instrumental.
