I spelled coughin' coffin' before: As soon as there was a pause in her hacking, Tina choked out, "Sorry, I can't stop coffin'." She imediately resumed her painful cough as she covered her mouth with both hands. I don't know why, but for some reason I have trouble with sound alike words. I know the difference, but I still tend to type the wrong word... such as know for no, dual for duel, etc... and vice versa. Even to, too and two, I tend to mess up on, even though I know the difference. The funny thing is, as I type this post, I didn't mess up at all on them... just like when I talk about my stuttering, I don't stutter.
