Even though I’m a complete snob when it comes to spelling and the proper use of typography, sometimes I get a little fuzzy on the finer points of grammar. My person, who is an English professor, received this birthday card:
First girl: “Where’s your birthday party at?”
Second girl: “Don’t end a sentence with a preposition.”
First girl: “Where’s your birthday party at, bitch?”
I find this to be a handy solution when unsure about proper sentence structure.
