Uhm, I came across this phrase when I was reading a story. I think "only" is used as an adjective here, but I haven't seen it before. I think it should have been followed by a noun , am I right? If this phrase is correct, please tell me about the usage of "only" in the following sentence:
"Being by himself was the only time when he felt he was being honest with the people around him, and then it was only because, of course, there weren't any."
