comma before 'and' [conjunction]: shoots them a glance and they

[Rabelaisian]

So the rule is to put a comma before a conjunction, in this case and, when it separates two independent clauses. But what if the writer prefers the brisk smoothness of not putting that comma in, in certain cases? For example:

He shoots them a deadly glance and they eventually get a grip on themselves.

Is that kind of rule-breaking okay?

Thanks.

The rule is that usually, or often, a comma is used before the "and"—not always. It depends on the sentence and how it would likely be spoken. A comma suggests a pause. In the sentence you give as an example, I'd place a comma after "glance".

So do you find yourself sometimes not putting a comma before and, even when it's separating two independent clauses?
