Please tell me if the comma is OK in:
We jumped on the Paris to Brussels train, and soon afterwards fell asleep.
Is there an online reliable guide to punctuation rules (esp. comma usage)?
dreamer2009... dreaming of a world without commas!
I also had a very hard time learning it without any assistance other than books, becase of the inconsistence in usage in them.
"and" in your sentence is a coordinating conjunction. Pedagogical grammar books claim they are to be preceded by a comma.
That is not entirely true.
When the clauses are short (What does the subjective term 'short' mean?) and well-balanced, you can drop the comma.
To draw an analogy, commas to sentences are often like brakes to cars.
