What's so grating about people is that some people use THEIR brains, while some people can't go THERE because THEY'RE too busy being great big ingrates. Book learnin' can help you to be 'good at grammar', but mostly it's an innate skill, an outgrowth of a narcissistic desire to not be an abject retard. Don't fret, though...the intellectual plebeians have already won, and next to nobody will ever recognize your grammatical deficiencies. Also, I'm day drunk as a mofo, so you should probably just ignore me...I'll put my NRTI cheerleader uniform back on in a few days.
