Stupid English Lessons

I generally love English, the lesson. However, when you are as old as me - 'smirk' - you think that you know all the grammar in that language, and you don't need to be taught. THIS IS A LIE! We are meant to be taught all that at an early age, but we aren't. Hardly anybody knows the difference between who and whom, me and I etc. We don't know cases! Feel good if you do. It is so annoying for an English freak like me! Don't use me and you in the nominative case! Use you and I!
