I know that a comma in front of the conjunction 'and' is usally set when and is connecting two independent clauses.
I can't decide, though, if the second part of the following sentence is, in fact, an independent clause:
Boredom comes, and unsolicited thoughts
I know that verb-only predicates exist, but does the adjective here count as a predicate so that I end up with two independent clauses?
edit: note that I would very much like to set the comma. I'm not looking for ways to spare me the comma.
