Truss, Eats, Shoots and Leaves -- Jerz: EL150 (Intro to Literary Study)
"In forty years he has had no reason to use an exclamation mark! He has no idea what it is for." (133)
I chose that particular quote because like Perekladin I use exclamation marks with a bit of trepidation. I'm never really sure what qualifies for one unless I'm writing dialogue and I want someone to yell. The exclamation point is probably my least used form of punctuation. After reading Truss I'm no longer so afraid to place an exclamation point at the end of a sentence, as long as its fitting.
