Now, how many have passed their driver’s test?
Punctuation is a lot easier if you think of the different marks as different road signs. Of course, there are rules to go along with these signs, rules we ignore at our peril. On the other hand, sometimes we don’t always strictly follow the rules. (Take it from a “lead foot.”)
Exclamation points [!] are like caution signs.
Commas [,] are like yield signs.
Okay, so you get the basic idea. It’s not a perfect system, but it’ a good way for me to remember proper punctuation.
