Q. What is the correct way to punctuate the following sentence: “Let’s face it, truth is sometimes stranger than fiction.” Is it correct to use the comma even though “Let’s face it” is an independent clause?

A. Your sentence is an example of a comma splice. Some readers will be distracted by it; some will consider it incorrect; a few will take it as one more sign that civilization is coming to an end. However, as Bryan Garner writes in Garner's Modern American Usage: “Most usage authorities accept comma splices when (1) the clauses are short and closely related, (2) there is no danger of a miscue, and (3) the context is informal.” That said, a dash or colon in place of the comma in your sentence would be uncontroversial.
