Overuse of Parentheses

I just wrote an email and, looking back over it, I can see I sadly overused parenthetical expressions. I had no less than seven sets of parentheses! Even the salutation included persons in parentheses; then, each of the four short paragraphs had at least one set included; luckily, however, I didn't find a way to put parentheses into my closing. If I had, it would only have completed my ruin. I need to invest in dashes!
