I get confused when the following happens:
Graham was angry because Lee burned the toast and Jennifer finished the milk.
Should there be a comma between 'toast' and 'Jennifer'?
The statement Lee burned the toast and the statement Jennifer finished the milk seem like they could function as standalone sentences. From what I have read, anything that functions as a standalone sentence is known as an 'independent clause', and when you separate two independent clauses with a coordinating conjunction such as 'and', you need to insert a comma.
However, Graham is angry because both of these things ruined his breakfast, but adding a comma would seem, to me, set off a separate statement which is unrelated to his anger.
Graham was angry because Lee burned the toast
And Jennifer finished the milk
Is the comma always included, never included, or sometimes included (depending on the idea being communicated)?
Thank you so much for reading this!
