Today the Apostrophe '

Alright. I admit. I'm a teacher that doesn't fully understand the use of apostrophes ...'? ...when it comes to plural things. However I found a website that has a handy dandy poster that managed to be usefully confusing. Don't believe me???? Check it out. I also have a really hard time with commas, (not to be confused with llamas! Watch out they spit!). Don't worry though there are only 21 rules on this webpage. Rule 12 is my favorite.  Rule 14 is my weakness. ..... I know!!!! I'm sorry. Maybe if they'd spend more time teaching grammar instead of recess we'd all be less confused. Hum, but then we'd all be obese...maybe they could just start punishing corporations for enticing us to eat unhealthy food with toys. WAIT! They already do that. Shucks. All the ideas are already taken. But I seriously digress. What was this post even about? OH! That's right apostrophes. . . yeah I don't like apostrophes....'s.... whatever. I'm going to get a cheeseburger.
