How much of a grammar nerd are you?
The Pedant’s Grammarian:
You may drive your family nuts, but you would make Strunk and White proud. You love enforcing rules just about as much as you love the rules themselves. For you, grammar truly is one of life’s greatest joys.
Like Wol, I suffer from wobbly spelling but my grammar is usually okay.
However, I usually mind my manners and refrain from correcting other people’s, except for an occasional reflexive reaction to seen instead of saw which I do my best to curb.
