Quick take

"Fields reserved from 4:30 to 8:30 for girl's softball."

I feel bad for the girl who's out there playing softball all by herself.

Dashes

I know you're all sitting up at night and thinking, "How do I know the appropriate length of dash to use in a given situation?" Good news, everyone! I'm going to explain it!

There are two types of dashes: en dashes and em dashes. An en dash is about the length of an "n." An em dash is about the length of an "m." See how they got their names? Very inventive. 

An en dash is pretty much a hyphen. We're not going to differentiate between the two because it's pointless. The one you need to know about--the one people screw up all the time--is the em dash. See how I did that there? It's an em dash in action!

Keeping up with the Joneses

Last names, like all other words, do not use apostrophes to indicate plurality. You'll see it all the time. Your Christmas cards will all have some corny picture of people you never see who are wearing matching outfits and smiling uncomfortably, and under the picture it will say "The Smith's." 

The correct response to this is "The Smith's what?" because an apostrophe indicates ownership, not plurality. It's just the Smiths. Why would the rule change because it's a name? This is stupid logic.
