a burglar breaking into the house. It is John who is drunk.
2) If you hear some strange noises from downstairs, don't panic. It is not
a burglar breaking into the house. It is John who has had too much to drink.
Are these grammatical?
Are they idiomatic?
Would a comma after John be correct?
I think the idea is to speak of John in a drunken state and the comma would
not be correct. His being drunk is essential information.
