pet peeve

I read a bunch of blogs, including many written by moms who are homeschooling their children. It really bugs me when they have this attitude of being educationally superior - and then do things like use the words compliment / complement incorrectly. Oh, and spelling errors. They drive me mad as well. It's just a small pet peeve . . . I know there are plenty of teachers who don't know the difference either . . . and my use of ellipses is probably somebody else's pet peeve :)
