10/10 baby!  I'm pretty finnicky about correct grammar.  I teach high school choir, and I'm pretty tough on my students on any writing they have to do for me, as far as grammar and spelling.  I've had multiple students ask me why I'm not an English teacher.  lol
Quick aside:  At the beginning of my first year at UMiami, a girl that eventually became one of my best friends related to me that she fancied herself a grammar Nazi, which I thought was cool.  Of course, we then talked online, and she proceeded to mix up your/you're and their/they're within the first 5 minutes of our conversation.  Neither her boyfriend or I will let her live that down.
