comma splice of life

A comma splice is one of those nasty English punctuation faux pas (a violation of accepted social norms).
A comma splice occurs when a writer uses a comma to separate two independent clauses instead of a semicolon or a coordinating conjunction.
EXAMPLE:  We drove across Mississippi, Alabama and Georgia all day, we still didn't reach Atlanta on time for the reunion.
CORRECT: We drove across Mississippi, Alabama and Georgia all day, but we didn't reach Atlanta in time for the reunion.
