Could of, should of

[ludog]

It makes me cringe when someone writes"I should of said..." instead of "I should have said...". I have seen this a lot lately on different Internet sites.

I know what you mean, it makes me cringe too.

This annoys me too, I've seen it on emails from top bosses too

Agreed. I also cringe (and correct) when DD says it.

That, and rampant apostrophe abuse; both get me riled.
