Don't worry about it too much....
People that don't understand the difference between "then" and "than" are more annoying as the two words are TOTALLY different, not an alternative spelling. One word is temporal while the other one is comparative.
A car is bigger THAN a ball.
A car is bigger THEN a ball.....yeah, then the ball does what? I was even at a stock market lecture once and the guy used "then" constantly as a comparison, "BHP has performed better then CRA"....arghhhh.....it was even in his handouts. Even more annoying was that he would have gone to school in the seventies...before the current dumbed down and Americanised generation, so he had no excuse! (The same guy was on ACA a few months ago)
To and too are also annoying. Too is a substitute for "also", so "I am going too", "I am going to" is an imcomplete sentence...where are you going to?
I blame the acceptance of mediocrity in schools, you can't tell a kid they are as dumb as dog do!
Well, must get back to my book..."see spot run..."
