i was almost run over once as a gar tried to jump a red light. i remember slamming my fists on the bonnet and yelling in a new york accent "hey I'm WALKIN' here!" exactly how dustin hoffman does in that film.
i remember getting cut quite badly once and the teacher was screaming and the friend who had accidentally cut me was freaking out and fussing.
again. i remember brushing my friend aside and saying "tis but scratch" quoting monty python. suddenly no one was panicking or freaking out. we were to busy laughing.
so again . do you use quotes? i know i do. why not use witty quotes to brighten the mood and releave the tension? next time your stuck for words. use a quote. its ok. better than not saying anything.
