Since we're on the subject of grammar and language, I wanted to point out what is perhaps my biggest pet peeve in everyday conversation: the phrase, "all the sudden" being used incorrectly in place of "all of a sudden." The former is grossly incorrect, and even the latter is better stated by simply saying, "suddenly."
Rarely a day goes by where I don't hear someone say this, and I often just ignore it in an effort not to offend the speaker. I'm assuming most people that say "all the sudden" simply mis-heard "all of a sudden" and integrated the incorrect result into their vernacular. So I try to be kind and let it pass... but it does grate at my soul.
