Think about this when submitting a synopsis letter. Like a resume, it should be succinct. I've seen some as long as 5 pages. They should touch on as many of the senses as possible. Keep those verbs active. A quick look in the "find" option will list where and how many "would" "could" "should" and "had" crept in when you weren't looking. With agents getting dozens of letters a day, a couple simple  rules will make your synopsis stand out.
