Effect/Affect and the use of "I" instead of "me"
"Bring a drink for your sister and I" *shudder*

[k2blader]

I suspect some folks use "I" as the default because they think it sounds more "classy"?

e.g. "Dahling, the chandelier will ride in the limo with Wadsworth and I."

I actually heard a teacher say, "I should have went."
