My goodness is the English language just HARD to figure out, isn't it? We have entirely too many words that sound the same but are spelled different and mean entirely too many different things. Take this example found on North Idaho ATV's website found by Megan's mom. They're (there/their) looking for (four) folks who registered their (they're/there) ATVs as snowmobiles which (witch) allowed (aloud) them to (too/two) ride on groomed trails.
My head hurts now. *sigh*
